Update to 3.3.2:

FFTW 3.3.2

* Removed an archaic stack-alignment hack that was failing with
  gcc-4.7/i386.

* Added stack-alignment hack necessary for gcc on Windows/i386.  We
  will regret this in ten years (see previous change).

* Fix incompatibility with Intel icc which pretends to be gcc
  but does not support quad precision.

* make libfftw{threads,mpi} depend upon libfftw when using libtool;
  this is consistent with most other libraries and simplifies the life
  of various distributors of GNU/Linux.
