  hadrian: pass -fno-omit-frame-pointer with +debug_info
  
  This patch adds `-fno-omit-frame-pointer` as C/C++ compilation flag
  when compiling with `+debug_info` flavour transformer. It's a sane
  default when you care about debugging and reliable backtraces, and
  makes debugging/profiling with bpf easier.
