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.
