    Fix vsyslog namespace (bug 18533).

    syslog functions (in POSIX) bring in the strong symbol vsyslog (not in
    POSIX).  This patch fixes this by changing this symbol from a strong
    alias to a weak alias.

    Tested for x86_64 and x86 (testsuite, and that installed stripped
    shared libraries are unchanged by the patch).  (vsyslog becomes weak
    in the static libraries, which is what's needed; the particular macro
    sequence in use leaves it as strong in the shared libraries, hence
    those libraries being completely unchanged, but it doesn't generally
    matter whether symbols exported from the shared libraries are weak or
    strong.)

        [BZ #18533]
        * misc/syslog.c (vsyslog): Define as a weak alias of __vsyslog,
        not a strong alias.
        * conform/Makefile (test-xfail-XOPEN2K8/syslog.h/linknamespace):
        Remove variable.
