Create KWSYS_PLATFORM_INFO_TEST macro 

This macro helps KWSys perform try-compile tests that extract 'INFO'
strings out of compiled binaries.  It works for CMake 2.6 and above.
On CMake 2.4 it always returns an empty list of information values,
so this should be used only as an optimization until 2.6 is required.
