More changes to come - I'm in progress of extracting and committing
modular changes from a mixed mess of changes I have in a WC.
In other words, yes, and I'll get to this at some point today.

Because it is possible for the files in question to be generated either
by autogen.sh --release, or by simple make. Depending on which happens,
it is appropriate to clean them at different times.
In a VPATH build, we can tell which mode they were built in based on
whether they are in the srcdir or the builddir. In a non-VPATH build, we
can't tell, so we just leave the cleaning until extraclean
unconditionally. (Though, I was talking with djames on IRC yesterday,
and we were thinking of recording whether the srcdir was in release mode
in build-outputs.mk, so we could do this better.)

The SWIG_??_DIR variables are only shorthand. And yes, sometimes they
are used, sometimes they are not. It doesn't really matter.
