libsemanage: Add crossbuild support

[Wookey]

libsemanage has no cross-build support. It builds for the wrong arch and fails to find libraries in multiarch directories.

This patch makes it use the HOST arch compiler and linker and multiarch libary paths, and also fixes an issue with the package not running make clean properly. I have a separate patch adding build-profile information which cannot be uploaded yet.

I am so sorry about duplicate work, but I think I have mostly uploaded this to raring already.

libsemanage (2.1.6-6ubuntu1) raring; urgency=low

  * Add a DEB_STAGE=1 build variant that skips ruby & python bindings.
  * Fix FTBFS with multiarched python2.7.

I see that this has been done in a slightly different way, so I need to double check if there is anything missing from the proposed (wookey's) patch.

Thanks for pushing this though.

applied in debian and synced into ubuntu. if there are any cross-building bugs, they should be reported in debian.
