Are you sure you don't wan't use y; or require y; in z.pm?? This means that your depending on y.pm being loaded somewhere else, which is a pretty big trap for someone, yourself probably, debugging latter.

In any case, if you only want to use it from within package z, you could do this in y.pm 

sub z::global_sub {
    print "global_sub working!";
}

If you don't like "G::global_sub", how about "::global_sub"? Think of '::' as a sigil (or twigil) for global. And as long as you use package declartions everywhere, you won't stomp on anyone elses namespace.
