Systemtap will fail with:
../usr/include/features.h:330:4: error: #warning _FORTIFY_SOURCE requires
compiling with optimization (-O) [-Werror=cpp]
| # warning _FORTIFY_SOURCE requires compiling with optimization (-O)
Use the same technique that eglibc uses to catch and correct the optimization
level, changing to -O2.
