    Mark debug sections referenced by kept debug sections

    If a debug section is referenced by a kept debug section, it should
    also be kept.

    Some targets, like mips, keep input files when there are some special
    sections, like .gnu.attributes, even if input file is unused otherwise.
    In this case, all debug sections are kept.  The new test will fail on
    such targets.  We can either fix those targets or XFAIL the test.
