in bsd.autotools.mk essentially makes this a no-op given that all the
old variables set a USE_AUTOTOOLS_COMPAT variable, which is parsed in
exactly the same way as USE_AUTOTOOLS itself.
Moreover, USE_AUTOTOOLS has already been extensively tested by the GNOME
team -- all GNOME 2.12.x ports use it.
Preliminary documentation can be found at:
http://people.FreeBSD.org/~ade/autotools.txt
which is in the process of being SGMLized before introduction into the
Porters Handbook.
Light blue touch-paper. Run.
Also, remove a redundant USE_GNOME definition, and fix some spacing.
libsamplerate support is easy to build in with a few quick patches, but
it hogs 100% CPU and then dies on a SIGSEGV. Someone might want to look
into that, because libsamplerate support would be neat for the crossfader
here.
