I meant the same obj tree with different source trees.  Ok, I agree that
this might not be a common case.  Is it easier to just not handle it?

It removes and re-creates the symlink (if you're using symlinks) for
each obj directory.  This is noticebly slow especially when using a NFS
v2 fileserver for the source tree.  To make things run faster, it'd be
nice to have a clean-obj-includes or obj-clean-includes target, but this
is obviously overboard.

How about (leaving out all the .if/.endifs):

	make share/mk
	make cleandir
	make obj
	make share/tmac

With this, any new tmac's get created in the tmac obj dir (if it exists)
and not in the source directory, which is one thing I was trying to
stop.  In fact, because we build the libraries with MKMAN=no we could
move the "make share/tmac" to after the libraries are built...
