    PowerPC64 stubs don't match calculated size

    After the PR 21411 fix, the linker generated .eh_frame for ppc64 glink
    can be edited by the generic code.  The sequence of events goes
    something like:
    1) Some object file adds .eh_frame aligned to 8, making the output
       .eh_frame aligned to at least 8, so linker generated .eh_frame FDE
       is padded to an 8 byte boundary.
    2) All .eh_frame past the glink .eh_frame is garbage collected.
    3) Generic code detects that last FDE (the glink .eh_frame) doesn't
       need to be padded to an 8 byte boundary, reducing size from 88 to
       84.
    4) elf64-ppc.c check fails.

        PR 21441
        * elf64-ppc.c (ppc64_elf_build_stubs): Don't check glink_eh_frame
        size.
