i386: stand: G/C `mbr_gpt*`; unhooked since 2011 in prefer of `gptmbr`

Specify NOLIBCSANITIZER in x86 bootloader-like code under sys/arch/

Set NOLIBCSANITIZER for i386 and amd64 specific bootloader-like code.

branches: 1.20.2;
Set NOSANITIZER in i386 mbr files

This is required to build these files and keep then functional with
enabled MKSANITIZER.

branches: 1.19.28;
Add empty LIBCRTI= as LIBCRT0 to build sa programs without installed DESTDIR.

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

branches: 1.18.4; 1.18.14; 1.18.18;
mbr.S and gpt.S want to reassign ., so don't use the integrated
assembler for now.

branches: 1.17.4; 1.17.6;
Change relay address for mbr and bootxx code to be 0x8800.
I'm not sure why I used 0x600, but I have a feeling that might
sometimes corrupt bios data.
0x8800 is far enough above 0x7e00 for a sector read to the latter address.

Remove extra trailing slash in ${S} path.

Prefer MACHINE_ARCH to MACHINE in some tests

branches: 1.14.2; 1.14.8;
Use ${TOOL_SED} instead if plain sed in Makefiles.

disable PIE for boot code.

branches: 1.12.58; 1.12.62; 1.12.68;
support MAKEVERBOSE

whitespace cleanup.

Use BUILDSYMLINKS & DPSRCS to simplify the creation of includedir symlinks.

Use -Wl,-Ttext,foo instead of -Ttext foo when using $(CC)

branches: 1.8.4;
Convert to using CC instead of LD, as LDFLAGS is for CC not LD.

branches: 1.7.4; 1.7.6; 1.7.8; 1.7.12;
merge ktrace-lwp.

branches: 1.6.2;
.BEGIN cannot have dependencies.

Force STRIPFLAG to be empty after bsd.own.mk is included, so that
any value set in /etc/mk.conf is overriden.

branches: 1.4.2;
Make this work without a populated destdir:
machine and x86 symlinks.
Include from right places.
Don't depend on LIBCRT0,etc.

Also for the bootxx programs, keep the ELF object during the build
process.

use nm(1) to output decimal values immediately, instead of relying on a
(non-working) sh(1) construct.

Reviewed by simonb & bjh21.

force nm addresses in hex and add 0x prefix before handing numerical
expression to the shell.

Master Boot Record (mbr) code:
mbr: boots active partition
mbr_bootsel: menu selection for partitions 1 to 4
mbr_ext: menu selection for partitions 1 to 4 and extended partitions
Based on code from sbin/fdisk/mbr_bootsel.
Needs a new fdisk to configure mbr_ext and correctly set default menu selection.(Not yet built by defaulat)
