The kernel build system supports parallel make and I guess all

The bottleneck is that we spawn so many make instances and each have
to read all the same makefiles and stat in total a zillion files
for a simple kernel build.
With a single Makefile we can run a single instance make where
we read all files only once and stat the same file only once.
