This is an option, yes: shipping the generated C files would remove the dependency to the Antlr executable. We might be able to place a git hook to do that, I'll discuss with the other guys here to see if they are up to it.
On the other hand, you can't do the dependency trick with make easily, since when you check out through git you basically have a pristine setup. We would have to do something like md5 the .g files and only trigger Antlr when the md5 has changed. I'm not aware of a simple way to do that.
