OK.  I thought that might be the case.  Thanks for letting me know.

Cool!  I’m in the process of looking everything over.  In the meantime,
I have some early questions and comments.

I think it makes sense to wait for the core-updates merge (which
shouldn’t be too far out).

I’ve reordered these changes a bit, and they are now ready to go.

These commits seem to be in the wrong order.  I think I can untangle
them, though.

I made some bigger changes here.  Mostly, I made use of
“substitute-keyword-arguments” to reuse more code from “ghc-8.4”.

Why do you use “patch” instead of “substitute*” to disable the failing
tests?  I see from your previous patches that you used to do it with
“substitute*”.

> #36807: this bug report, removing three deprecated packages

Since we already had a back-and-forth for these, they’re almost
certainly fine.

This seems reasonable to me, though I suppose it would be better to only
skip them when building for i686.  It looks like we only do this
rarely (e.g., the “icu4c” package), so maybe it’s not a big deal.

Is there any more info about “ghc-trifecta”?  The other two have nice
comments that tell me that upstream is aware of the problem, and that it
might be fixed in the future.

Thanks for putting this branch together!
