reduce the size of gdb-6.6-buildid-locate.patch
    
    While working on the Fedora tree I noticed that the upstream function
    build_id_bfd_get is renamed to build_id_bfd_shdr_get.  The body of the
    function is not changed at all though.  This is done in the patch
    gdb-6.6-buildid-locate.patch.
    
    Carrying this sort of change in the Fedora tree just makes it harder
    to maintain our downstream patches (merge conflicts) so I propose that
    this small part of gdb-6.6-buildid-locate.patch be reverted, we leave
    the function name as build_id_bfd_get.
    
    When regenerating the patches gdb-6.6-buildid-locate-rpm.patch also
    changed, but not really: the location of a hunk changed slightly as a
    result of the cleanup in the earlier patch.  There's no actual content
    change in this second patch.
    
    There should be no changes in the functionality of a Fedora GDB build
    after this commit.
