auto-disable FFTW quad precision on RISC-V

[bedroge]

I ran into this error when compiling FFTW on RISC-V:

checking for sinq in -lquadmath... no
configure: error: quad precision requires libquadmath for quad-precision trigonometric routines

It's already disabled for Arm and POWER, this PR also disables it for RISC-V.
