We don't actually probe for javac in all circumstances, so if you have javac installed, but don't have antlr4 installed, and you're on Mac OS X, then you'll get a message that javac is missing, even though that's wrong. To fix this, let's just be a bit more generic in the message, so that it's the same no matter what part of the lexer tests you're missing. cc https://www.reddit.com/r/rust/comments/3m199d/running_make_check_on_the_source_code_says_javac/
