I've tried compiling SeaBIOS with gcc and binutils from ports the
following way:

# pkg install binutils gcc48
# PATH=/usr/local/bin/:$PATH gmake V=1 CC=gcc48

And the result is the same, the binary compiles fine but fails to work
as expected.

On the other hand, when using the crossgcc toolchain from coreboot the
resulting binary seems to be working fine.

I've looked at the gcc48 and binutils ports, and they don't seem to
contain any patches that would affect SeaBIOS, but I'm not sure:

https://svnweb.freebsd.org/ports/head/devel/binutils/files/
https://svnweb.freebsd.org/ports/head/lang/gcc48/files/

What does 'readelf -a out/bios.bin.elf' tell you, for each build where
you either override, or aren't overriding, CC with coreboot's
i386-elf-gcc or pkg's gcc48 and/or LD from FreeBSD's base or pkg?

payloads/external/SeaBIOS/seabios $ gmake CC=gcc48
LD=/usr/local/bin/ld &>/dev/null ; readelf -h out/bios.bin.elf | egrep
'OS/ABI'
  OS/ABI:                            UNIX - FreeBSD

payloads/external/SeaBIOS/seabios $
PATH=/home/idwer/coreboot/git/coreboot/util/crossgcc/xgcc/bin:$PATH
gmake CROSS_PREFIX=i386-elf- &>/dev/null ; readelf -h out/bios.bin.elf
| egrep 'OS/ABI'
  OS/ABI:                            UNIX - System V
