autotools: use recursive automake to support out-of-source builds.

When performing an out-of-source build (in particular, with "make
distcheck"), the rules that we were using to replace @LIBDIR@ and
friends were failing. Automake does a lot of path magic in its rules,
but not within the shell commands themselves, so ultimately we wound
up with some confusion between the source and build directories.

Rather than hack around this problem in the top-level Makefile.am,
I've converted the project to a recursive build, where the top-level
Makefile.am delegates to Makefile.am in the subdirectories. This
over-complicates things, but does fix the out-of-source build. Why?
A guess: because the path magic works better in "." than elsewhere.
