fftw: minor update and major refactoring
- Unify the "single" and "float" variants, which are the same thing. - Enable threads and openmp wrapper by default (they are very small). - Don't use sse on i686, as I'm quite sure we have no warrant for that. Cf. http://en.wikipedia.org/wiki/Pentium_Pro - Disable static libs (big, no indication we need them). - I tested most builds using fftw (they build OK).
