    [GOLD] powerpc64le-linux fails to link large Linux kernel

    Gold attaches stubs to an existing section in contrast to ld.bfd which
    inserts a new section for stubs.  If we want stubs before branches,
    then the stubs must be added to the previous section.  Adding to the
    previous section is a disaster if there is a large gap between the
    previous section and the group.

        PR gold/20878
        * powerpc.cc (Stub_control): Replace stubs_always_before_branch_
        with stubs_always_after_branch_, group_end_addr_ with
        group_start_addr_.
        (Stub_control::can_add_to_stub_group): Rewrite to suit scanning
        sections by increasing address.
        (Target_powerpc::group_sections): Scan that way.  Delete corner
        case.
        * options.h (--stub-group-size): Update help string.
