A few Travis change

Initialize the git submodules to the index (I'm not sure what they're initialized to right now).
Move exports to before_script, and print out compiler version.
Invoke check directly (the shebang and x permissions should take care of it).
Remove the sleep on warnings, it slows down Travis.
