Fix GOTPCREL for x86_64

[Andreas Jaeger <aj at suse dot de>]

We have the appended patch in our binutils already for quite some time
but unfortunatly the original testcase was lost.  I'm not sure whether
we forgot to send it - or to commit it, I can't find anything on it:-(

Brief explanation:
This fixes generation of GOTPCREL relocations, they had sometimes the
wrong offset.

This version should be safe even for non-ELF targets.

Ok to commit?
