1. All Makefiles that use ARM_APCS_FLAGS add -marm unconditionally and
bsd.own.mk also adds it for gcc only (so we end up with 2 -marm for gcc).
Just add -marm unconditionally in bsd.own.mk in ARM_APCS_FLAGS and remove
it from everywhere else.
2. gcc-8 now warns about thumb internetwork in APCS mode. This does not make
sense because the documentation says that this flag does not make a
difference in apcs mode, but might produce larger code in non-APCS mode.
So we just add it to silence the warnings.

Consistently use ${RELEASEDIR}/${RELEASEMACHINE} instead of
${RELEASEDIR}/${MACHINE} (Paul Ripke)

branches: 1.20.14;
centralize vers.c building for standalone programs.

GC more logic that was intended for GCC <4.8 (or !LLVM)

Same as before (-marm implies -mno-thumb), but now the condition was flipped

branches: 1.18.2; 1.18.4;
include bsd.init.mk to get Makefile.inc

branches: 1.17.2;
Don't use ${MACHINE} but zaurus instead.

Add empty LIBCRTI= as LIBCRT0 to build sa programs without installed DESTDIR.

XXX: probabry we should have bsd.saprog.mk or something.

Move flags for ARM's APCS ABI into a common variable. Add some forces to
deal with limitations in the Clang <-> LLVM backend interaction to pick
the correct ABI and target assembler.

Use -marm for clang builds, too.

fix more -mno-thumb.

Add CPPFLAGS+= -mno-thumb -mno-thumb-interwork

Add -fno-unwind-tables

This change arm, armeb, earm, earmeb, earmhf, earmhfeb so all builds that
share a MACHINE_ARCH for userland so that except for etc, will produce
identical sets.

usr/include/machine now points to usr/include/arm

Force abi/float-abi/cpu
Only allow to build on little-endian.
Force MACHINE to be zaurus.

Support to read the kernel from local file system.

ex. boot path:/mnt/card/netbsd

Apply the following patch submitted by Evgeniy Ivanov:
http://mail-index.NetBSD.org/tech-kern/2011/12/15/msg012226.html
http://mail-index.NetBSD.org/tech-kern/2011/12/17/msg012229.html

- add 'ls' op to struct fs_ops to support ls command on each fs,
enabled by -DLIBSA_ENABLE_LS_OP and SAMISCMAKEFLAGS+="SA_ENABLE_LS_OP=yes"
in libsa
- split sys/lib/libsa/ufs_ls.c into UFS specific part and MI part (ls.c)
that opens the target fs and calls fs-depedent XXX_ls() functions
- add a ls op for ext2fs
(all other fs than ufs and ext2fs don't have actual ls ops yet)
- replace existing MD ufs_ls() calls with this new MI ls()

The original patch was written for i386 and ext2fs.
zaurus zboot has been tested by nonaka@.
ews4800mips and x68k loaders have been tested by me (with several fixes).
landisk might be okay since it was almost copied from i386.

XXX1: "ls" op in fs_ops looks a bit inconsistent, but we will be able to
replace it with real fs ops like readdir if it's really worth
XXX2: someone might have to check sys/arch/ia64/stand/efi/libefi/efifs_ls.c

Defer bsd.own.mk include after NOMAN.

Drop bootprog_maker (formerly enabled by -M) and bootprog_date (formerly
disabled by -D) from the output of newvers_stand.sh. Change -D to the
inverted logic, so that it adds the date to bootprog_rev in ().

Change all platforms accordingly. -D is added if MKREPRO is not yes and
wasn't present before. Platforms that didn't use -D don't depend on
MKREPRO now either.

Introduce .WAIT into the cleandir rule for blasting the libsa/libkern/etc.
trees, because it can race with the libsa/libkern/etc. makefiles' own
cleandir rules. I think I've found all of the uses of the offending idiom...
Closes PR 43360.

Use <bsd.klinks.mk> to create ${MACHINE} and ${MACHINE_ARCH} symlinks.

fix make release.

Added zboot from OpenBSD.
