The config.test thingy is simply to make life easier for the wast
majority of users. The users still have the option to tell configure
which helpers they want if the automatic tests fails.
What I have seen in other projects for solving this problem is usually
the following approach:
Each sub-program (or in some cases linkable module) is a project of it's
own, with it's own configure. If this configure finds that the
requirements is not met the sub-project Makefile defaults to build (and
install) nothing.
