enable support for using the system portaudio library. The latter also corrects a long standing bug that prevented using config.status to regenerate src/Makefile. As a result of the above, I've taken Benjamin's *_LOCAL_CONFIGURE_ARGS idea and propagated its usage to the other place where ac_configure_args was being set directly. Removed old stuff from lib-src/Makefile.in and made the library locations for portaudio and portmixer like the rest (a symlink in lib-src). Reworked portmixer's configure.ac to properly detect host apis.
