Guido Falsi 8b7324ed3f core/buildsystem: check the actual compiler being version 
Make compiler check use the output of the actual compiler being
used as reported by the CC variable, instead of unconditionally
running the "gcc" binary.  Also only run the check if the compiler
is gcc or a cross-compile gcc.
