[Buildroot] [git commit] mongrel2: Add comments to avoid use of github call

[Thomas Petazzoni]

commit: http://git.buildroot.net/buildroot/commit/?id=502a08b681c9cc96603e5de6e22bfa892f078c03
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

As the comment says, we don't want to uses the github helper, as we
would end up with a generated tarball, which is not the same one as the
one linked with the releases.
