fftwQuad: Mark unsupported on aarch64 

https://gcc.gnu.org/onlinedocs/gcc/Floating-Types.html
https://fftw.org/fftw3_doc/Precision.html



Building fftw with quad precision requires libquadmath via gfortran. On
aarch64, libquadmath is not supported due to GCC's __float128 type not
being supported on that platform.
