Message:

Pass system include dirs via -isystem, for correct ordering

We need those directories to be considered after any -I specified by
the user, otherwise ordering is a problem.

By default, GCC doesn't produce warnings for system headers.
We want those warnings anyway, so we enable them specifically.
