[Buildroot] [PATCH v5 4/5] dependencies.sh: XBMC needs java on the host

[Maxime Hadjinlian <maxime.hadjinlian@gmail.com>]

XBMC uses a code-generator which is build in two phases:
In the first phase SWIG is used to parse C++ header files that define the API.
SWIG outputs an XML file that contains a complete description of the structure
of the API.
In the second phase, the XML file is ingested by a Groovy (Java) program that
then creates C++ code that forms the bridge to the scripting language (Python).

The second phase is why we need java on the host.

You can learn more at the XBMC's wiki:
