This commit will not completely remove all Imake files, specifically
those for sections that have not been completed yet.
Also, the databases dir has been moved to databases-delete-later until
we have everything building and installed properly.
The osf/ stuff includes uil, wml, etc - we expect these to be provided
by Motif, and make no attempt to build them in CDE, so no need for
them.
The only program in utils/prog/ is an ancient verion of lndir that we
do not need for CDE. If you need lndir for some reason, use the
laters version from Xorg, usually installed via the xutils-dev
package.
