Flesh out the platform variables, rather than bogusly setting BUILD
and TARGET to HOST most of the time.

This doesn't give us any better cross-compiling support, but it's a
step in the right direction.

Also, I added a comment describing the proper meaning of BUILD
vs. HOST vs. TARGET, and which one to test in various parts of the
source tree.
