gdb: Additional fix for MKCROSSGDB=yes build

Disable `info` itself to fix environment(== timestamp, probably)-
dependent build failures as cross-gdb.

Now, only `native-gdb` builds *.info files.

Thanks martin@ for report and test!

tools/gdb: Use MKGDBSERVER consistently, NFC for now

disable sim on powerpc

copy the rest of the includes and stop using --with-foo=${TOOLDIR} because
it breaks static linking (it picks the tools version of the libraries when
cross building sun2)

For mknative, we need the native versions of MPFR and MPC, so provide them
in the link line, to override those in ${TOOLDIR}/lib

mknative-gdb: Generate *.info by using makeinfo(1) from pkgsrc

Unfortunately, our in-tree makeinfo(1) (latest GPLv2 version) is
too old for this purpose :(

changes for new gdb (disable zstd, find mpc/mfpr/gmp differently)

gdb/mknative: Preset yes to rename(2) checks

It must be better to have this workaround here, rather than in external.
(Thanks uwe@ for suggestion!)

Confirmed that the same files generated as before.

tools/gdb: Drop working dir for mknative from generated files

Migrate -I${.OBJDIR}/.native/include from CPPFLAGS to CCADDFLAGS for
this purpose.

No binary changes for native binaries as far as I can see.

backout previous; cross build needs native gmp

mknative support for gdb-13.2

Set ac_cv_func_sigprocmask=yes as the symbol renaming confuses the
configure script on architectures that don't provide a compatibilty
symbol, e.g. RISC-V

branches: 1.40.6;
grab the gdbserver version

Add gdbserver

force libexpat since the autoconfig test are not cross-compile friendly
(they try to link with /usr/lib/libexpat.so in the compiler invocation).

Disable mpfr to make MKCROSSGDB work again. The problem is that the default
(auto) finds the mpfr library in tools, but then when it tries to build using
the proper headers it does not find it anymore since we don't install it
(like the native build does not find it).

branches: 1.36.2;
Create a new bsd.hostinit.mk file and put the build definitions for all host
programs there; make all Makefiles that use bsd.hostprog.mk include it.
Namely turn off MKREPRO and don't make lint, man pages, info files etc.
Remove the Makefile.inc files that contained these same settings, and
remove the settings from Makefile.host

PR/53238: Robert Elz: Disable MKREPRO in tools; the host compiler might
not support the necessary options. This is done thusly:

1. Set MKREPRO=no in Makefile.host. This handles all the Makefiles that
use it and don't include bsd.own.mk.
2. Create Makefile.inc and set MKREPRO=no in it. Change the Makefiles that
include bsd.own.mk, to include bsd.init.mk which includes Makefile.inc
first. This will also allow us to control other tools options from a
single location if we need to.

XXX: pullup-8

branches: 1.34.2;
we want no-iconv for the tools build, but we want iconv for mknative.

Changes for gdb-8.0.1

Adjust to gdb-8.0.1 which uses c++
XXX: quoting of variables that contain paths and versions is broken.

--disable-nls does not work in gdb subdir, so add am_cv_func_iconv=no to
configure env. Fixes build on FreeBSD.

Fix the host build of aarch64 with clang

Define __STDC_{LIMIT,CONSTANT,FORMAT}_MACROS in CXXFLAGS.
The problem is that the gnulib interception of <stdint.h> and <inttypes.h>
does not really work because we implement those internally with
<sys/inttypes.h> and <sys/stdint.h> and those internal headers are used
by other internal headers *before* they get a chance to be intercepted
(where the __STDC_ macros are defined).

Another way to fix this is to move the inclusion of the other headers
in <stdint.h> and <inttypes.h> outside multiple inclusion protection.

branches: 1.27.2;

gdb.old is no more.

Fix tools build on Solaris with MKCROSSGDB=YES.

rework the main SUBDIR list here as suggested by enami. put .WAIT on
the same line as the target that needs to wait, but before the target,
rather than on the previous line, which led to confusion and an error
being introduced in the previous change.

Fix parallel build. Analyzed & patch provided by enami@, thanks!

disable only parallel make.

Disable parallel build, which always fails at compiling itable.c / interp.c.
Only affect MKCROSSGDB=yes.

MACHINE_CPU is "mips" not "xxmips".

Fix the logic for --disable-sym. Hi uwe!

Use CPPFLAG_ISYSTEM.

Disable sim for mknative unless it's known to work (configure's
default is to enable sim if there's support for the cpu).

The current list of "known to work" contains arches with G_SIM_OBS
already set: powerpc, powerpc64 and mips.

There's arm support in sim, but committed configs for arm do not have
G_SIM_OBS set, so I'm not enabling it here.

There's SH support in sim, but it fails to build out of the box, and
since we didn't build SH sim support for gdb 5.3, we keep it disabled.

Other arches shouldn't be affected, as there's no support for them in sim.

Pass preset configure "cache" vars in the environment not only to the
top-level configure, but to ${MAKE} configure-host as well.

Add more vars (for readline mostly) so that there's no configure
warnings about tests skipped b/c of cross-compilation.

Use -isystem to add ${DESTDIR}/usr/include to the search path.

gdb comes with its own copy of GNU readline 5.x, but
-I${DESTDIR}/usr/include stuffed at the beginning of the command line
makes it find our compat readline/readline.h (emulating readline 2.x)
that conflicts with the readline 5.x includes.

Makes README.mknative instructions actually work instead of failing
midway b/c of conflicting tilde_expand() prototypes.

Configure using --with-separate-debug-dir=/usr/libdata/debug.
(The various MACHINE-specific configurations will need to be regenerated.)

Explicitly pass "--prefix=/usr" to configure so that DEBUGDIR and
LOCALEDIR point into /usr rather than /usr/local.

Support .native in an objdir, so I can keep more than one around at a
time.

Support for mknative machinery.

add gdb53 as a host tool for use as a crossgdb
replaces gdb50 from toolchain on archs which use gcc3

Nowadays, mknative-gdb puts files into external/gpl3/gdb/lib,
instead of external/gpl3/gdb/bin/gdb.

Also, we need to nbmake-MACHINE in external/gpl3/gdb in order to
build dependent libraries correctly.

Update to working instructions.

thx mrg for the build_install suggestion.

branches: 1.5.42;
mknative for gdb7

Note that nbmake-MACHINE native-gdb writes files under src, so this
step needs to be done in a writable src tree.

Notes for how to do the mknative dance (based on the gcc one, but with
unnecessary steps removed).
