s390x - gcc-3.4.1 - glibc-2.3.3

[Norbert <nthiebau at tampabay dot rr dot com>]

Hi all,

I successfully built a cross for s390x on a x68_64 (Suse 9.1, vanilla)
Using crosstool-0.28-rc37

and re-using the s390.demo s390.dat and s390.config, slightly modified.
The only non-triavial thing was to add "--disable-multilib " as an extra
parameter, without it a link fails on ctri.o. Since I didn't need the 32
bits lib, the above worked for me :-).

 echo Done.

I ran the resulting hello world program on a tao-linux-s390x running
under hercules (a mainframe hardware emulator).
