Subject: [PATCH] Build: Restore support comments for Android 4/iOS 7 from
 c40934f3d0

We're nearing QUnit 3.0 release, and given IE 11 support remains,
there was ultimately no code removed for Android 4-6 and iOS 7-8.
While I can't integrate these in CI these and won't proactively test
them around releases, we can continue to allow others to support these
and report issues if need be.
