New description:

 In times of multi-core machines it is not too uncommon to compile projects
 like QGIS with "make -j9" or even higher. This does not work, however, as
 the compile process bails out. Not a big thing, lowering it to -j6 makes
 it work, but the error shows a build dependency problem in the makefiles
 that should be fixed.

 Here is a part of the log:
