Subject: [PATCH] perf test: Use -Wp,-U_FORTIFY_SOURCE for tests built with -O0
If EXTRA_CFLAGS has "-Wp,-D_FORTIFY_SOURCE=2", the build fails with:
error: #warning _FORTIFY_SOURCE requires compiling with optimization (-O) [-Werror=cpp]
Use "-Wp,-U_FORTIFY_SOURCE" instead of "-U_FORTIFY_SOURCE" for tests
built with -O0.
