Thanks for those hints.

I have now managed to bootstrap a compiler on that machine, but
success at running programs is somewhat limited:

tkoenig@gcc-fortran:~/Tst$ which gcc
/home/tkoenig/bin/gcc
tkoenig@gcc-fortran:~/Tst$ cat hello.c
#include <stdio.h>

int main()
{
   printf ("Hello, world!\n");
   return 0;
}
tkoenig@gcc-fortran:~/Tst$ gcc hello.c
tkoenig@gcc-fortran:~/Tst$ ldd ./a.out
./a.out: /lib/powerpc64le-linux-gnu/libc.so.6: version `GLIBC_2.34' not 
found (required by ./a.out)
         linux-vdso64.so.1 (0x00007a16a4510000)
         libc.so.6 => /lib/powerpc64le-linux-gnu/libc.so.6 
(0x00007a16a42c0000)
         /opt/at15.0/lib64/ld64.so.2 => /lib64/ld64.so.2 
(0x00007a16a4530000)
tkoenig@gcc-fortran:~/Tst$ export LD_LIBRARY_PATH=~/lib64:/opt/at15.0/lib64/
tkoenig@gcc-fortran:~/Tst$ ls
Segmentation fault (core dumped)

@IBM folks: I would appreciate if you gave me access to a system
which actually worked, together with the necessary information,
so I can actually do what I volunteered to do.

Right now, I appear to be just wasting my time.
