@boegel looks ok

Hi Ken,

Without this, builds with ictce/3.2.2.u3 or ictce/5.2.0 are broken.

that last one is a good catch. Can you elaborate?
Does it affect also 5.1.1 and other toolchains or what?
I have to admit I was surprised for 5.2.0; it wouldn't affect easily the bioinformatics packages but many other applications would suffer (notably for the fellows who are busy in material science and affiliated domains).

@fgeorgatos: The reason this broke is because of #518, i.e. we're a lot stricter now w.r.t. setting $LIBFFT, i.e. we only set it if the required libraries are actually there.
Before, the $LIBFFT was broken for ictce/3* and ictce/5*, but nobody noticed because $LIBFFT was not used by any of the builds using those toolchains.

So, "the FFTW libs they provide are different", as per #easybuild discussion among the imkl APIs/ictce toolchains;

this now triggers me to provide the grand Pull Req. for ictce 5.2.0, since the chances of success have increased :-)
