 I imagine the same will work for fftw-3-single?

 Normally, yes. This is a fairly general universal build framework
 solution: the code is duplicated in subdirectories corresponding to each
 arch, then separately configured with the right arch flag and compiled
 therein, then the results are joined through lipo into a universal file.
 It should be satisfactory for build processes that use -M or -E or any
 other option not compatible with multiple arch switches in gcc.
