Hi there, ghosts of Chicken past.

Although it's still officially unsupported, Peter Bex's revamp of the
makefile system after 4.6.0 seems to have enabled reliable parallel
builds.  I am now able to build repeatedly at -j2, -j3 and -j4.   On
the quad-core system I tested on, -j4 is 3.4 times faster than -j1.
