Title: Rakefile: closure_compile force 32bit mode only when java supports it

Some Java installs don't have '-d32' flag (e.g. OpenJDK which is standard
for some Linux systems), and the closure_compile fails because of forcing
that flag. Test, and only run in faster 32bit mode if supported, or
else just run with no flag (default mode).
