[PATCH] Adjust `pc-fp.exp' for ppc64/s390x (PR 12659)

[Sergio Durigan Junior <sergiodj@redhat.com>]

While regtesting 7.4 against 7.5 branch on ppc64/s390x RHEL 6.3, I
noticed this failure.  The patch which introduced this failure was
committed because of:

      http://sourceware.org/bugzilla/show_bug.cgi?id=12659

On x86*, the output of `info register pc fp' is:

    info register pc fp
    pc: 0x400520
    fp: 0x7fffffffc490
    (gdb) PASS: gdb.base/pc-fp.exp: info register pc fp

On ppc64/s390x, it is:

    info register pc fp
    pc             0x10000658       0x10000658 <main+20>
    fp: 0xfffffffd120
    (gdb) FAIL: gdb.base/pc-fp.exp: info register pc fp

Since this difference in the output does not seem to be an error itself,
the patch below just adjusts the testcase to match this kind of output
as well.  It does not fail on x86*.

OK?
