problems building for cris architecture

[Jesse Kipp]

Thanks! I ended up using -save-temps. It looks like the definition for
_syscall6 was missing from libc/sysdeps/linux/cris/bits/syscalls.h. A
patch had already been committed, but not made its way into release
yet.

Now during the linking of ldso I've got:

ldso.o: In function `_dl_dprintf':
ldso.c:(.text+0x474): undefined reference to `__errno_location'

(plus in a bunch of other functions)

It looks like maybe there is a file missing during the linking...
Should __errno_location be coming from the pthreads library, or am I
barking up the wrong tree? Just to make sure I compiled for another
architecture (x86) and it was fine, but I can't track down where the
difference in the arch-specific files is.
