We already have a fix for Ardour and mod-host on the staging branch, but it will be some time till it's merged. This patch adds threaded variants for fftw/fftwf and changes both Ardour and mod-host to use them.
This patch can be easily reverted once the staging branch is merged. What do you think? ~~ Ricardo PS: I only built mod-host so far because I don't have enough space at the moment for building Ardour.
