    PR28172, bfin_pcrel24_reloc heap-buffer-overflow

    bfin pcrel24 relocs are weird, they apply to the reloc address minus
    two.  That means reloc addresses of 0 and 1 are invalid.  Check that,
    and fix other reloc range checking.

            PR 28172
            * elf32-bfin.c (bfin_pcrel24_reloc): Correct reloc range check.
            (bfin_imm16_reloc, bfin_byte4_reloc, bfin_bfd_reloc): Likewise.
            (bfin_final_link_relocate): Likewise.
