RCW+MJW:
Modify Makefile's to use $(MAKE) instead of just make so that one can
use the make job scheduler to compile in parallel. E.g.
make -j2 serial
This works fine for AMBER10 - currently there are issues with
Amber_tools due to dependencies not being specified properly. I.e.
nab tries to run code as part of the build process which fails if that
code has yet to be compiled.
Example timings for amber10 serial build:
1 cpu Pentium-D 3.2GHz = 6m04s
2 cpu Pentium-D 3.2GHz = 3m25s
