    Mark success return value as volatile to work around rescheduling

    Resolves #15921

    The test case nptl/tst-cleanup2 fails on s390x and power6 due to
    instruction sheduling in gcc.  This was reported in gcc:

    http://gcc.gnu.org/bugzilla/show_bug.cgi?id=58034

    but it was concluded that gcc is allowed to assume that the first
    argument to sprintf is a character array - NULL not being a valid
    character array.
