Fix the csound5 install phase.

At some point, pkgsrc started setting a different MAKE_ENV in the
install phase than in the build phase.  This caused scons to report that
"the build action changed", which caused scons to rebuild csound5 and
install it with a broken configuration.

This hack saves MAKE_ENV to a file in WRKDIR, then uses that file to set
the environment in the install phase.

Add DragonFly support.
XXX The SCons usage sucks.

Log message:
Initial import of csound5 version 5.01, a software synthesizer and
sequencer.

Csound is a software synthesis package in the tradition of so-called
music-N languages, among which the best-known is Music V.  It consists
of an orchestra- and score-driven executable, written in C for
portability.  Since Csound is a computational language, it is highly
flexible and efficient; complexity is gained only at the expense of
computation time.

To do:
- fix pthread issues in csound5 (is breaking realtime audio)
- use options.mk framework for various modules
- enable portaudio module (requires audio/portaudio-devel)
- port portmidi to netbsd
