Very good. TY for short and precise answer.

Now, for build flags macros and variables, I want to add some options
to the default one. I am not sure how to add options in a clean way.
These extra flags are used because I build with Intel Compiler:

export CFFLAGS= '-xHost -mavx -fp-model precise'
%configure
   CFFLAGS="${CFLAGS:-%optflags}" ; export CFLAGS ; \
   ........

Is above the the best way?
