Not all programs work with 'make' to build, or do not rely on that for the
multitask build.
For example, go_oo or openoffice use another way. When I have to test their
builds, I always enable the multiprocess build, which works perfect. Maybe we
want to have something overridable enough, so the openoffice expressions can
take advantage of that NUM_CORES.

For my side... I never felt the big need of multicore builds in nixpkgs;
whenever I'm testing the build for a big program in a multicore machine, I edit
the expression temporarily to get that advantage.
