nia eab927a4f0 split fftw package into -long and -quad precision variants
the package previously used PKG_OPTIONS for this, but PKG_OPTIONS
are harmful in the case that they effect the resulting ABI of
library packages. this way, things that actually need fftwl and fftwq
can depend on these sub-packages.

this also fixes fftwq on NetBSD by making it pull in libquadmath.
another thing about PKG_OPTIONS for library components is that
they mean certain components don't get tested...

FFTW is a C subroutine library for computing the discrete Fourier transform
(DFT) in one or more dimensions, of arbitrary input size, and of both real
and complex data (as well as of even/odd data, i.e. the discrete cosine/sine
transforms or DCT/DST).
This package contains the long double precision floating point FFTW
libraries.
