You're using cygwin, so you'll suffer from the great cygwin slowness. Even
when the build system does everything right you'll find it slow. The exact
same HW will build Rockbox MUCH faster if you ran Linux, and that's also true
for Linux in a VM on that machine.

There may of course be areas in the build that can be further improved though
that could speed things up.

We're not using any autotools. This is plain traditional make magic!
