[oe] [PATCH 1/2] fftw: build all configurations by one recipe

[Andreas Müller]

* avoids conflicts installing same files into sysroot
* for packages requiring a specific version of fftw: simply add fftw to DEPENDS
* no need for some distro decision - recipes depndong on fftw take what they
  need
* each executable is packed into an own package to avoid dragging in all
  libraries
