systemtap: Systemtap can not be build w -O0 optimization
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.
