We should not include glibc headers from BIOS code which can't rely on glibc at
runtime.
This patch fixes the following build breakage on 64-bit:
CC bios/e820.o
In file included from /usr/include/features.h:387:0,
from /usr/include/unistd.h:26,
from include/kvm/util.h:12,
from bios/e820.c:5:
/usr/include/gnu/stubs.h:7:27: fatal error: gnu/stubs-32.h: No such file or directory compilation terminated.
make: *** [bios/bios.bin.elf] Error 1
when built without the 'glibc-devel.i686' package on Fedora, for example.
