If you can't calculate a comprehensive list of either the contents of
the prefix pattern or the suffix pattern, you've got problems.

If you _can_ calculate one or the other, then you can use the "include a
makefile and re-exec" trick to automate its behavior.  Suppose you can
calculate all the suffixes that you'll use: write a rule that builds a
makefile containing an implicit rule for each suffix.  Then include that
makefile.  If the makefile doesn't exist, make will build it using your
rule, then re-exec itself to read it in.

You need to have the makefile target you create depend on something that
will change when the list of suffixes change (for example, the main
Makefile or whatever).
