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.
