 Both the fftw-3 and fftw-3-single ports have --enable-fma in their
 configure.args. These should be removed, as they are incorrect for Intel
 builds, and replaced with the appropriate platform-specific args.

 Suggested args:[[BR]]
 PPC: --enable-fma --enable-altivec[[BR]]
 Intel: --enable-sse OR --enable-sse2 (for fftw-3-single, and fftw-3,
 respectively)

 It might also be nice to add '-O3 -fomit-frame-pointer -fstrict-aliasing'
 to the configure.cflags-append -- most folks using FFTW are going for
 speed; might as well build for it. (These flags were found on the FFTW
 benchmark site: [http://www.fftw.org/speed/Pentium4-3.06GHz/] and
 [http://www.fftw.org/speed/G5-2GHz-macosx/])
