Use PRINTOBJDIR to get the object directory of libc and use that with -I.

Add -D_REENTRANT

For cerror, allow -I../libc to allow inclusion of any assym.h, if up.

Let libposix and librt have their own version of __cerror (__posix_cerror and
__rt_cerror). This enables each library (including libc) the oppurtunity to
make its __cerror hidden and avoid being called via the PLT. No user visible
differences to no need to bump the minor number.

MAKEVERBOSE messages

Rework how dependency generation is performed:

* DPSRCS contains extra dependencies, but is _NOT_ added to CLEANFILES.
This is a change of behaviour. If a Makefile wants the clean semantics
it must specifically append to CLEANFILES.
Resolves PR toolchain/5204.

* To recap: .d (depend) files are generated for all files in SRCS and DPSRCS
that have a suffix of: .c .m .s .S .C .cc .cpp .cxx

* If YHEADER is set, automatically add the .y->.h to DPSRCS & CLEANFILES

* Ensure that ${OBJS} ${POBJS} ${LOBJS} ${SOBJS} *.d depend upon ${DPSRCS}

* Deprecate the (short lived) DEPENDSRCS


Update the various Makefiles to these new semantics; generally either
adding to CLEANFILES (because DPSRCS doesn't do that anymore), or replacing
specific .o dependencies with DPSRCS entries.

Tested with "make -j 8 distribution" and "make distribution".

Use ${HOST_SH}

Make the generated .S files depend on ${.CURDIR}/sys/Makefile.inc.

Invoke makelintstub with CPP in the environment.

Use ${NETBSDSRCDIR}/some/path instead of ${.CURDIR}/../../some/path (etc).
(Reduces make output by ~ 20%)

Don't run makelintstub if MKLINT=no.

Update to match libc's new .S build rules.

Actually profile system calls.
Problem and most of the fix reported by Anders Hjalmarsson in PR 4976; libposix
mentioned by Chris G. Demetriou.

branches: 1.10.2;
Some cleanup; g/c unneeded lint stub files.

branches: 1.9.2;
make this build again after the mips->mipse? transition

Generate PSEUDO-stubs for chown(), fchown() and lchown(). Also, change the
prefix of the actual syscall from "posix_" to "__posix_".

sh makelintstub, rather than trying to execute it directly

Instead of creating a .ln for each syscall stub, create one (big) .ln
per class of syscall stubs. This is much more efficient (though it's still
pretty inefficient).

This also fixes a problem with syscall.h and DESTDIR which was pretty
well buried in the old implementation.

From Chris Demetriou <cgd@pa.dec.com>.

use CPPFLAGS instead of CFLAGS

branches: 1.4.2;
Back out BUILDDIR and NOINSTALL changes.

DESTDIR -> BUILDDIR

Use toolchain-driven PIC flags to build .so files from assembler source,
instead of inline tests on ${arch} and duplicate rules.

Add POSIX compatibility library.
