Subject: fio: move _FORTIFY_SOURCE to only when optimization is turned on
X-Git-Tag: fio-2.16~5

fio: move _FORTIFY_SOURCE to only when optimization is turned on

When compile with debug, without the proper -O flag the compiler complains:
/usr/include/features.h:331:4: warning: #warning _FORTIFY_SOURCE requires
compiling with optimization (-O) [-Wcpp]
#  warning _FORTIFY_SOURCE requires compiling with optimization (-O)
Moving _FORTIFY_SOURCE to optimized compile option.
