Bug#528680: libfftw3-3: FFTW 3.3 provides MPI support, disabled in Debian builds

[Alexei Matveev]

Package: libfftw3-3
Version: 3.3-1
Followup-For: Bug #528680


MPI support is disabled in FFTW builds despite being provided
by the upstream.

README.debian say this about MPI support:

    Unlike fftw2, there are no MPI based libraries at this time. Upstream
    should release them soon. Once upstream adds MPI support, the Debian
    package will include it.

The upstream version 3.3 of FFTW profides MPI support that can be enabled
by adding --enable-mpi to configure script:

     build-arch:

This has been tested by building FFTW package from Wheezy distribution
on Debian Lenny.
