Subject: [PATCH] Handle building individual targets better.  It's still
 broken; the only way to be sure the build works correctly is to do a 'make
 all'. But with these changes, it's easier to test individual targets.  In
 particular, ensure that the vnode file systems are mounted before writing to
 them.

Ensure that we don't get CVS directories on our floppies.

Use kgzip instead of kzip to compress the loader.  This saves a few
kB.

Remove some test cruft.
