 The config script detects arch fine when run outside of Macports:

 I don't believe the macros the script looks for are GCC macros; they seem
 to be defined by python.  I tested GCC v4.2-apple, v4.9-mp, v5-mp, v6-mp
 and v7-mp and none of them defined those macros.  I'm still investigating,
 but right now it looks like there's no issue with Mozilla's configure
 script, but there's an incompatibility with Apple's python2.7 while
 Macports' python2.7 works.
