Comment(by jmr@…):

 OK, so gmp and mpfr are correctly applying your build_arch. This may not
 be so easy to fix in the gcc ports; you can't just pass '-arch i386' in
 CFLAGS like normal, since it ends up trying to use those flags with the
 generated compiler, which doesn't understand -arch (and -m32 has similar
 problems because of multilib.)
