    PR 21412, get_reloc_section assumes .rel/.rela name for SHT_REL/RELA.

    This patch fixes an assumption made by code that runs for objcopy and
    strip, that SHT_REL/SHR_RELA sections are always named starting with a
    .rel/.rela prefix.  I'm also modifying the interface for
    elf_backend_get_reloc_section, so any backend function just needs to
    handle name mapping.
