RE: new build system

Actually, current versions of GNU-make are very recursion-friendly:

from the NEWS for version 3.78 of GNU-make:

* A "job server" feature, suggested by Howard Chu <hyc@highlandsun.com>.

  On systems that support POSIX pipe(2) semantics, GNU make can now pass
  -jN options to submakes rather than forcing them all to use -j1. The
  top make and all its sub-make processes use a pipe to communicate with
  each other to ensure that no more than N jobs are started across all
  makes. To get the old behavior of -j back, you can configure make
  with the --disable-job-server option.

If it didn't work, I wouldn't have checked it in :-)

Actually, make -j should work much better with the single makefile. It can
parallelize the entire build, not just the bits within a single directory.
