Have you tries using the --x-includes, -x-libraries, --includedir, --libdir 
flags?

Using them is better than fiddling with the CFLAGS because they place
various items in the correct order on the command line (at least they
used to, it's doubtfull that these flags are used much these days, so
they might have bitrotted...)
