If you are cross compiling then the version of package System for the
target would have a System.Name to reflect the target.
I'm not sure why this is a problem for any 'closed' compiler, as the
vendor must know the exact target (OS + processor + switches).
I can understand there is a problem for 'open' compilers, as anyone can
build for any OS+processor+switches and make the system name anything -
even erroneous!
