[Buildroot] [PATCH 1/1] package/avahi: fix building against gobject-introspection

[aduskett at gmail.com]

From: Adam Duskett <Aduskett at gmail.com>

Currently, if gobject-introspection is built before avahi, avahi will fail
to build with several undefined reference errors due to several .libs
directories not being in the PATH when linking the .gir file.

To resolve this issue, do the following if gobject-introspection is selected:
  - Add gobject-introspection to AVAHI_DEPENDENCIES
  - Add --enable-gobject to AVAHI_CONF_OPTS
  - Add the appropriate directories to GIR_EXTRA_LIBS_PATH.

Fixes:
