* fftw: patch configuration file to remove search for xlc_r compiler
when compiler not gcc
FFTW assumes there are only 2 compilers: gcc and IBM XL. When
building threaded fftw, the configuration file is looking for
the threaded IBM XL's xlc_r compiler when the compiler is not gcc.
The PGI compiler is not gcc.
