    PR21167, relocation sections not included in groups

    This fixes a wart I've known about for years, but haven't done
    anything about because BFD treats relocation sections as an adjunct to
    the section they relocate.  SHF_GROUP on the section thus implicitly
    applies to its relocation section(s), but it is an error that the
    reloc sections aren't part of the group.

on older object files, we get
