[Cerowrt-devel] speeding up builds

[Dave Taht]

I finally acquired a machine with 32GB of ram, an intel 3930k (6
cores), and an SSD.

Without the toolchain rebuild, but after a make clean (to rebuild the
packages and kernel), it's about 28 minutes.

I can see that it is possible to parallelize things more to maybe chop
another 30% of of things...
