Subject: [PATCH 1/2] build: Don't conflict with the user's CFLAGS

This uses the variable MAINT_CFLAGS to set the project's flags so that
the user can set CFLAGS as an environment variable or as an make
argument without any conflicts.

This can be problemtic with the build environment in some distros.
