[PATCH] build-many-glibcs.py: Add some s390x glibc variants.

[Stefan Liebler]

There is a s390x configure check which checks the architecture level set.

This ALS influences e.g. which ifunc variants are needed or which one is
the default variant or if the symbol will be an ifunc-symbol at all.

The ALS also enables to use the gcc builtins for e.g. the round function
in libm and others.

Therefore this patch adds some glibc variants which are using different
architecture level sets for s390x.
