0ed36875f4 Ensure GCC does not use FP registers in integer code.
I think all we really need is -fno-sse2.
I really don't like cluttering up the compiler invocation,
but this bigger hammer will fix reported problems for now.

bcd106e18b - Factor out -nostdlib to an upper level Makefile.inc.
- Now that bsd.prog.mk deals with programs linked with -nostdlib
  better, and has a notion of an "internal" program, use PROG
  where possible.  This has a good impact on the contents of
  .depend files and causes programs to be linked with cc(1).

XXX: boot2 couldn't be converted as it's actually two programs.

Tested on:	i386, amd64

a4a62f5d1f First round of cleanups to sys/boot/ makefiles:
- do not use PROG for what's not a real C program,
- use sys.mk transformation rules where possible,
- only create the "machine" symlink on AMD64,
- removed MAINTAINER lines in individual makefiles,
- added the LIBSTAND defitinion to <bsd.libnames.mk>,
- somewhat better contents in .depend files.

Tested on:	i386, amd64

5aef48a16b Add -mpreferred-stack-boundary=2 to CFLAGS for i386. This and libstand
reduces /boot/loader from 163840 bytes to 155648 and pxeboot from 165888
bytes to 157696 bytes.

48a0c4ea04 Mega i386 loader commit.
- Don't hard code 0x10000 as the entry point for the loader.  Instead add
  src/sys/boot/i386/Makefile.inc which defines a make variable with the
  entry point for the loader.  Move the loader's entry point up to
  0x20000, which makes PXE happy.
- Don't try to use cpp to parse btxldr for the optional BTXLDR_VERBOSE,
  instead use m4 to achieve this.  Also, add a BTXLDR_VERBOSE knob in the
  btxldr Makefile to turn this option on.
- Redo parts of cdldr's Makefile so that it now builds and installs cdboot
  instead of having i386/loader/Makefile do that.  Also, add in some more
  variables to make the pxeldr Makefile almost identical and thus to ease
  maintainability.
- Teach cdldr about the a.out format.  Cdldr now parsers the a.out header
  of the loader binary and relocates it based on that.  The entry point of
  the loader no longer has to be hardcoded into cdldr.  Also, the boot
  info table from mkisofs is no longer required to get a useful cdboot.
- Update the lsdev function for BIOS disks to parse other file systems
  (such as DOS FAT) that we currently support.  This is still buggy as
  it assumes that a floppy with a DOS boot sector actually has a MBR and
  parses it as such.  I'll be fixing this in the future.
- The biggie:  Add in support for booting off of PXE-enabled network
  adapters.  Currently, we use the TFTP API provided by the PXE BIOS.
  Eventually we will switch to using the low-level NIC driver thus
  allowing both TFTP and NFS to be used, but for now it's just TFTP.
