    Re: gas: add visibility support using GNU syntax on XCOFF

    tc-ppc.c: In function 'ppc_comm':
    tc-ppc.c:4560:40: error: 'visibility' may be used uninitialized in this
function [-Werror=maybe-uninitialized]

    With that fixed we hit lots of segfaults in the ld testsuite.

            PR 22085
    bfd/
            * xcofflink.c (xcoff_link_input_bfd): Don't segfault on NULL
            sym_hash.
    gas/
            * config/tc-ppc.c (ppc_comm): Init visibility.
