[Yhc] Location of generated files

Good :) You are welcome to use the Make library as well - I
deliberately wrote it to target all compilers and Cabal.

True. I would have thought that few of these projects put Haskell
sources at the root level, then their important objects underneath.
However, if we restrict to cleaning .hi, .hbc etc we should be ok. At
the moment there is no yhc clean command, so it can be done later.

That all relates to invoking Yhc on Haskell files. This mainly
involves building a list of dependent modules, then extracting rules
from this dependency information. The make library is already in the
tree (src/libraries/make), and I'll hopefully have committed the
Make2.hs tonight.

Thanks
