The mystery still stands.

I suggest to separate variables here, and time the byte compilation
alone.  Try this:

  cd lisp
  find . -name "*.elc" -delete
  make compile

and time the last command.

With the current trunk, you can do "make -j6 compile" instead of the
last command, and it should be about 3 to 4 times faster.
