Benjamin Hipple e2b44b3170 fftw: support multiple src URLs
The fftw download page provides both an HTTP and FTP endpoint for downloading release tarballs:
http://fftw.org/download.html

Since some users may have difficulty fetching via FTP through corporate
firewalls, we should provide the option to get it over HTTP as well.
