Here's an example of what new PKGBUILDs look like if we rely on the
"provides" semantics.
You see how this works even if say, haskell-containers is moved out of the ghc set?
Our deps will continue to be correct.
We should never have relied on cabal2arch to fake "provides" in the first place :)
The key now will be ensuring that GHC's provides list is 100% accurate.
