[PATCH] S/390: correct plt entry size for 31bit

Hi,
I've noticed that the entry size value in the section header for a s390
(31bit) plt section is wrong - currently it is always set to 4.
I've discussed that already with Martin and he wasn't sure whether
that can be changed safely. Hopefully someone on that list might give us a
hint.
Obviously that change leads to coexisting binaries which according to
readelf have different plt entry sizes.
I don't see a problem here but maybe there are tools relying on that
value which we aren't aware of.
So here is the trivial patch. I've tested it by building a 31bit executable
and checking whether readelf returns the correct value for its plt entry sizes.
Bye,
-Andreas-
