[Bug ada/37977] New: System.Address size stays 64 bit with -m31

[krebbel at gcc dot gnu dot org]

Ada currently doesn't bootstrap on s390x due to a pointer size mismatch when
building the 32 bit version of a-except.o:

You need to add multilib support for s390 to gcc-interface/Makefile.in, see
for example SPARC/Solaris.

Ok. I'm bootstrapping a patch which mimics what has been done for Power.
