package/ogre: new package

Ogre needs host-swig with pcre support when python interpreter is
present on the target.
Otherwise the build stop with the following message:
"SWIG:7: Error: PCRE regex matching is not available in this SWIG build."

Ogre has been tested using the SampleBrowser binary but some demos
are not working due to missing optional dependencies (nvidia Cg plugin).
