I suppose the configure script is stable enough now to do something like
this.
It appears you didn't change all the AC_TRY_RUN() uses. Does it only
work for a limited set of features?
You should also add an explanation of how to do cross compiling to the
INSTALL file. A list of all the values to be set is very useful.
What happens if a value is guessed wrong? It should still be possible
to do "make test" somehow, otherwise the building result may not work
unexpectedly.
