[RFA] rs6000-nat.c fetch_register error condition.

[Elena Zannoni <ezannoni@cygnus.com>]

I am trying to break down the Altivec patch in smaller pieces that
don't require a ptrace interface.

I thought this bit had been approved by Kevin in
http://sources.redhat.com/ml/gdb-patches/2001-11/msg00564.html

but it wasn't.

Kevin, OK to commit?

        * rs6000-nat.c (fetch_register): Don't error out unless the
        register number is really bogus.
