2.25 Backport Request of two testsuite related patches

[Jiong Wang <jiong dot wang at foss dot arm dot com>]

Hi Tristan,

  Is it still OK to backport two ld testsuite patches to *2.25* branch?

  Without this two fixes, there will be some noisy when doing testing
  with 2.25 binutils.

  I verified these two patches apply cleanly on 2.25 branch. And as they
  are pure testsuite changes, there is no functional change on toolchain
  behavior.

  Thanks.

    ld/testsuite/ld-unique: Fix running unique tests on ARM

    The @ character is a comment character on ARM, so use % instead. Also
    use a wider glob for matching ARM targets to make sure the test gets
    run.

    ld/testsuite/ChangeLog:

    2014-10-30  Will Newton  <will.newton@linaro.org>

        * ld-unique/unique.exp: Use a wider glob for matching ARM
        targets.
        * ld-unique/unique.s: Use % instead of @ in .type directive.
        * ld-unique/unique_shared.s: Likewise.
