Various fixes to the source, depend and export targets: All automatically

generated files in the src tree (except some things in post_modules) are
really generated now. When --disable-binary is used, most configure tests
will fake success, so that make depend isn't short-circuited in modules that
can't be compiled on this machine. Also a little less noise in the depend
targets so that errors are easier to spot.
