nice! The only thing that is worrying is the question how we make sure
these bad path's are enforced.

E.g. a recipe not honoring our CPPFLAGS might silently pass this check
(while before it was hardcoded into the compiler). My proposal would be
to extend the sanity check and grep the compile log for gcc and -ibad
and fail if gcc exists but -ibad does not occur?
