FFTW single-precision library built
Until now, we were using the `--enable-single' configure-time option of FFTW to build its single-precision library. The reason was that according to the output of `./configure --help', this was equivalent to `--enable-float'. However, the single precision library wasn't being built. As a result, on systems that already had it, SExtractor would use the system's library and on other systems, it would simply not pass the configure step. With this commit, we are now using `--enable-float' which fixes this problem and installs the `libfftw3f*' libraries (showing that it is not equal to `--enable-single'!). Also, some optimization flags were added to hopefully make it faster. This issue was found thanks to Zahra Sharbaf and Hamed Altafi. This fixes bug #56588.
