[sr-dev] Makefile and environment XXFLAGS

[Victor Seva]

Hello,

I have a bugreport[0] about hardening [1] and how I try to pass this
flags to the build system [2][3]

Is there any proper way to configure this flags? Should I try to
modify the Makefile.def for use the environment flags and not clean
their values?

Cheers,
Victor
