Could you please explain why this change was made?
Why was the old way "insanity?"

The old way helped with endian issues.
See http://thread.gmane.org/gmane.os.apple.macports.devel/6859/focus=6862

It also made fortran use possible.
gfortran seems to work with -m64 but does not recognize -arch x86_64.

It also precludes the use of gcc-mp-* for building 32/64-bit universals.
