Even in the cross compilation environment, the cppunit stuff should
build and link OK.  Running the tests on the host machine is a
different problem, but solving that isn't specific to cppunit.  We'll
also have the same problem with all of the "make check" tests.

There's no easy way to remove the cppunit stuff.  You'd have to edit
a good percentage of the Makefile.am's.  I think that we ought to
build the unit tests.  They should be runnable once everything is
installed on the host system.

Thanks for your offer!

In general, is OE the answer, or are there other cross development
environments that we should be looking at?  It looks like OE was
designed to solve the "build an entire system image, including kernel,
boot loader, etc".  That may be overkill for the PS3.  On the other
hand, if OE solves the "configure in the cross development
environment", then maybe it is the easiest way to get going.

Ultimately with the cell, I suspect that we need a "dual
cross-compilation" environment since you need two tool chains
installed, one for the PPE and one for the SPE.
