I've been exchanging email with dwmw2 about this for months now.  Now that 
I've got some spare time I'm rebuilding Firmware Linux as a cross-compile 
setup using qemu.  Results are a bit mixed, though.  Building current uClibc 
cvs as of half an hour ago:

  CC ldso/ldso/ldso.oS

                 from ./include/bits/uClibc_errno.h:35,

./libpthread/linuxthreads.old/sysdeps/x86_64/pt-machine.h:27:24: error: 
asm/prctl.h: No such file or directory

Changed pt-machine.h to include sys/prctl.h and it made it much farther, then 
it died with:

  CC libc/sysdeps/linux/common/prctl.os
libc/sysdeps/linux/common/prctl.c:13: error: conflicting types for 'prctl'
./include/sys/prctl.h:28: error: previous declaration of 'prctl' was here
libc/sysdeps/linux/common/prctl.c:14: error: conflicting types for 'prctl'
./include/sys/prctl.h:28: error: previous declaration of 'prctl' was here

At which point I stopped for dinner.  Just now getting back to it...
