Fix the -pthread problem in case the option gets removed again. This
patch involved patching the core auto* routines in KDE to accept the
PTHREAD_* variables in the environment, with fallbacks. We decided the
easiest way to implement this in ports was to generate configure instead
of risking incorrect generation at port configure time.
Said patch has already been committed to HEAD in KDE and as such will be
removed with the 3.2 upgrade once it is released.
Ports using Makefile.kde that shouldn't be using them (i.e. non-KDE
modules) have this support commented out due to lack of patch.
