    PR20886, looping in ppc64_elf_size_stubs

    The PR20886 binary is large enough that there are two stub sections
    servicing .text (which is 88M).  It so happens that between one
    iteration of sizing and the next that one stub section grows while
    the other shrinks.  Since one section is always growing, the loop
    never terminates.

    This patch changes the algorithm to not update previous size on
    shrinking, once we go past a certain number of iterations.

        PR ld/20886
        * elf64-ppc.c (ppc64_elf_size_stubs): Make rawsize max size seen
        on any pass past STUB_SHRINK_ITER.
