[Buildroot] [git commit] opengl: correct detection of virtual packages having no dependencies

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=14470b325935ee8a0ef8b73b33827ab633c1366f
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

I believe the original intent was to make it that the configure step
for the opengl virtual packages fails if there is not at least one
dependency. This patch fixes the logic so that it actually fails if
dependency list is empty
