bsd.own.mk: rename to CC_WNO_ADDRESS_OF_PACKED_MEMBER

Provide a single variable
CC_WNO_ADDRESS_OF_PACKED_MEMBER
with options for both clang and gcc, to replace
CLANG_NO_ADDR_OF_PACKED_MEMBER
CC_NO_ADDR_OF_PACKED_MEMBER
GCC_NO_ADDR_OF_PACKED_MEMBER

Using the convention CC_compilerflag, where compilerflag
is based on the full compiler flag name.

apply some GCC_NO_ADDR_OF_PACKED_MEMBER.

PR 54394: do not compile in experimental SCSI support by default,
#ifdef it out as it breaks some machines. Based on a patch by
Ulrich Teichert, with #ifdef instead of comments suggested by nonaka@.

branches: 1.30.14;
centralize vers.c building for standalone programs.

branches: 1.29.4; 1.29.8; 1.29.12;
Don't set -mmultiple or -mno-string for PowerPC, the difference is too
small to really matter and it sometimes even increases the size.

branches: 1.28.2;
Add empty LIBCRTI= as LIBCRT0 to build sa programs without installed DESTDIR.

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

Use <bsd.klinks.mk>
Use ${_MKTARGET_LINK}

branches: 1.26.2; 1.26.4;
Support load kernel from SCSI HDD with siop. It copy from bebox. (EXPERIMENTAL)

branches: 1.25.4; 1.25.8;
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.

Switch remaining platforms to modern CPP for assembler.

branches: 1.23.6; 1.23.8; 1.23.10;
Warning options should be in CFLAGS, not CPPFLAGS.

Change the prep bootloader to reach over into the
powerpc/stand/mkbootimage directory for the magic.h file.

branches: 1.21.28; 1.21.38; 1.21.42;
Generate an intermediate boot.elf with symbols.

branches: 1.20.4; 1.20.6;
General fixups:
1) Fix support for the powerstack E1. This machine needs to use the 8259
directly, and cannot use the prep interrupt vector register. Place a
quirk entry in the table for the machine.
2) Add a new com0_vreset boot image. The vreset code only works on a few
machines, and breaks others like the 7025-F40. Its only limitedly useful
when used with the com0, so just make it an optional image the user can
install by hand if they want.
3) Bump the bootloader to 1.8 with the above change.

branches: 1.19.4;
More major bootblock changes:
1) Rewrite vreset.c completely. Saves about 1k, and now it sets the
screen up much better. Previously the resulting video mode looked bad on
my CRT, and my LCD wouldn't even recognize it as a valid mode. Now it
looks reasonably good and my LCD can talk to it.

2) Call vga_reset unconditionally in the setup process to fix the onboard
VGA. If you have a VGA and use the serial console, this will allow you
to still use the VGA device for getty/wscons. Tested on a 7248 with VGA
and a 7043 without VGA.

3) Change filesystem.c to use nullfs rather than ufs and cd9660. We
don't actually need an fs at all, but it would take a major rewrite to
get rid of them completely. This saves about 6KB on the bootloader.

4) Bump version to 1.7.

Clean up the bootloader a little bit. Get rid of some unused code,
set the makefile to build the bootloader without the DB_MONITOR stuff by
default, as it is primarily for debugging. Reduces bootloader size by
about 8k.

More ro src breakage.

merge ktrace-lwp.

branches: 1.15.2;
Rework depends so this works w. -j after .BEGIN fixes

boot-loader can find attached kernel again.

reduce program size.

Use 32bit daddr_t.

Use ${HOST_SH} instead of `sh'.

If necessary, pull in <bsd.sys.mk> to get the definition of HOST_SH;
Makefiles that pull in one of (most of) <bsd.*.mk> will get this anyway.

Define LIB{CRT0,C,CRTBEGIN,CRTEND} as nothing, we don't need to link
against them.

Add -ffreestanding

Set NOxxx= before <bsd.own.mk> is pulled in (even indirectly).
Otherwise the appropriate MKxxx=no won't be defined .
