D'oh again.  I did mean to add a dependency at some point in time
(or maybe was it a .PHONY entry?)..

Anyway, the way the rule is now, if $LN_S is `cp', source files in
$(INTERFACE_DIR) newer than in `.' will not get copied, which is bad.

And I did mean to write one rule and mention the docs about multiple
outputs, so that Harald could write the rule with proper dependencies in
place (e.g., a stamp file, so the rule is not run every time).  Ah, yes.

It's IMVHO a bad idea to take bug submitting away from the user actually
experiencing the problem.  At least in general, for several reasons.
