PREFIX, LIBDIR and JACK_VERSION are fetched from the environment

waf complains about missing source files, e.g.:

   could not find 'jack/*.h' in /home/adi/jack2/common

ant_glob fixes the problem

waf complains about missing features in the builder, so let's add some.

For the sake of completeness, here's an example error message:

The misc module is no longer available, but we have a subst_pc builder
now. Let's use this instead.
