commit 9ec85a27138aefcd3fc35ddbd7727f384fe299b1

    Fix corrupted .eh_frame section with LTO and --gc-sections.

    Backport from trunk:

    When --gc-sections is turned on during an LTO link, the .eh_frame sections
    from deferred files are processed before those from the replacement files.
    As a result, the section end-cap from crtendS.o is placed ahead of
    the .eh_frame data from the replacement files. This patch fixes the bug
    by skipping the layout of the deferred sections during GC pass 2.
