[Buildroot] [PATCH] pulseaudio: fix build with orc

[Arnout Vandecappelle (Essensium/Mind)]

From: "Arnout Vandecappelle (Essensium/Mind)" <arnout at mind.be>

The configure script gets orcc from pkg-config, which sets it to /usr/bin/orcc
instead of $(HOST_DIR)/usr/bin/orcc. So set the path explicitly instead of
relying on pkg-config.

While we're at it, also add an explicit enable/disable to configure.

Ideally, this should be fixed in orc-0.4.pc, but I'm not sure what would
be the best way.
