 While trying to upgrade fftw-3 @3.2.1_2+gcc43 the configure script fails
 with the following error:
 {{{
 checking for Fortran 77 name-mangling scheme... configure: error: in
 `/opt/local/var/macports/build/_opt_local_macports-
 trunk_dports_math_fftw-3/work/fftw-3.2.2':
 configure: error: cannot compile a simple Fortran program
 }}}

 config.log shows:
 {{{
 configure:25700: gfortran-mp-4.3 -o conftest -pipe -O2 -arch i386
 -L/opt/local/lib -arch i386 conftest.f -lm
 f951: error: unrecognized command line option "-arch"
 f951: error: unrecognized command line option "-arch"
 }}}

 I have not tested it for other gcc variants and I am aware that this is
 related to changes in 1.8
