Unfortunately there are many special cases, including libraries that
require symbols in the executable, so its not possible to do that.  For
this reason the "static library not found for dependency" is just a warning.

We can add such a compile test ourselves.  Of course it might add to the
compile time if we do it for every dependency, but perhaps we can do one
with all the dependencies and if it fails loop on single dependencies to
give a better error.
