the headers like linux/*.h or asm/*.h
have to be replaced with the right headers from machine/*.h
on BSD OSes.

I think the libc won't be a problem, as long as GNU ld is supposed to be
able to link files of different binary formats.
I think you can produce ELF binaries with the Darwin's binutils,
but I didn't check that point. But you can still install antoher
binutils version, able to produce ELF and mach-O binaries,
if you compile them from the Apple tarball.

I'll think of it :-)
I already did something related to this.
I have a emulation for BSD under Linux.It's not complete and 
works only qith simple programs...
But for now, I want to have a functional PPC emulation in qemu
and see it integrated before I start something like this.
It would be a good train for me to know better BSD and improve my BSD
emulator :=)
