    PR22509 - Null pointer dereference on coff_slurp_reloc_table

    This extends the commit 4581a1c7d304 fix to more targets, which
    hardens BFD a little.  I think the real underlying problem was the
    bfd_canonicalize_reloc call in load_specific_debug_section which
    passed a NULL for "symbols".  Fix that too.
