    Re: PR26580, Size and alignment of commons vs as-needed shared lib

    Some MIPS targets, for reasons I didn't analyse, use the larger common
    symbol in a shared lib rather than a smaller common in an executable.
    That doesn't seem unreasonable, so allow that to pass for pr26580-2.

    bfin-elf complains about not supporting copy relocs, but it's quite
    silly to want a copy reloc for common symbols, so leave the fail
    there.  mn10300-elf and score-elf both fail the test with "PHDR
    segment not covered by LOAD segment".  Other tests fail similarly so
    one more doesn't hurt.  The failure is a consequence of supporting
    dynamic objects but setting EMBEDDED in ld scripts.

            PR 26580
            * testsuite/ld-elf/pr26580-2.sd: Accept undefined symbol.
