I just tried compiling for 64 bit s390x, this is what I found so far:

- in include/stdint.h, the definitions for *int_fast*_t conflict with
  the 64 bit ones

- mmap.c does not compile because _syscall6 is defined only for i386,
  alpha, cris, mips(64) and parisc but not for the other ten architectures.

- syscalls/time.o does not compile because __NR_time is not defined for
  alpha, ia64 and s390x

- making klibc cross compilable with 'make CROSS_COMPILE=prefix-' would be 
  a nice and trivial addition

- compile time warnings: see below

more later when I actually manage to run something
