Subject: Fix platform file for GNU/Hurd
Currently (both in cmake 2.6.x and cmake 2.8 as of its latest rc5), the
GNU.cmake platform file used for GNU/Hurd systems is not complete. In
particular, it needs the rpath-link flag definition, needed for properly
compiling in all the cmake setups; in particular, its miss causes the failure
of the ExportImport unit test, which instead works correctly with the proposed
patch. Also, the patch provides some more definitions, a bit close to the
Linux oones (given the base toolchain is quite close anyway, GNU-based).
