    PR23653, ld SIGSEGVs when attempts to link sparc object with x86_64 library

    This patch improves dynobj selection.  This allows the testcase in the
    PR to proceed further before segfaulting due to other bugs in the
    sparc backend.

    ../ld/ld-new --eh-frame-hdr -m elf_x86_64 -shared -o bug.so.5 bug.o
./libc.so.6 ./crtendS.o
    ../ld/ld-new: sparc architecture of input file `bug.o' is incompatible with
i386:x86-64 output

    ../ld/ld-new: bug.c:(.text+0x8): undefined reference to
`_GLOBAL_OFFSET_TABLE_'
    Segmentation fault

        * elflink.c (_bfd_elf_link_create_dynstrtab): Match elf_object_id
        too when choosing dynobj.
