commit: https://git.buildroot.net/buildroot/commit/?id=48934ed0a97b7baee7ad8fbfb19e449024cdda9d
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Reiterate once more that <packagename>_PATCH variable can point
to an arbitrary URL, not just to a path relative to <packagename>_SITE.

While we're at it, also explain that the patch should be added to the
.hash file.
