Use new NANO_LOG to put the logs some place reasonable. Also, share

the object directory among all builds where it makes sense. When
building with NANO_CPUTYPE, separate that out to its own object
directory. Put disk files in their own directories.

This should make having multiple variants of the same architecture
saner.
