since you are using gcc, there are -fsyntax-only and -w which should provide 
less verbose builds. But there are only very few portable compiler options (like 
-I, -D) and to my knowledge none address warnings.

You could of course redirect all compiler stderr output to /dev/null and thus 
get rid of it, i.e. add 2>/dev/null to your make calls. But this will make 
debugging build failures harder later on.
