wasm-cross failures: Cabal complains about splitmix
Cabal finds itself unable to build a plan. But only sometimes.
Examples I've seen recently:

Resolving dependencies...
cabal: Could not resolve dependencies:
[__0] trying: ghc-platform-0.1.0.0 (user goal)
[__1] trying: base-4.17.0.0/installed-4.17.0.0 (dependency of ghc-platform)
[__2] trying: hadrian-0.1.0.0 (user goal)
[__3] trying: hadrian:+selftest
[__4] trying: QuickCheck-2.14.2 (dependency of hadrian +selftest)
[__5] next goal: splitmix (dependency of QuickCheck)
[__5] rejecting: splitmix-0.1.0.4 (conflict:
base==4.17.0.0/installed-4.17.0.0, splitmix => base>=4.3 && <4.17)
[__5] skipping: splitmix-0.1.0.3, splitmix-0.1.0.2, splitmix-0.1.0.1,
splitmix-0.1, splitmix-0.0.5, splitmix-0.0.4, splitmix-0.0.3, splitmix-0.0.2,
splitmix-0.0.1, splitmix-0 (has the same characteristics that caused the
previous version to fail: excludes 'base' version 4.17.0.0)
[__5] fail (backjumping, conflict set: QuickCheck, base, splitmix)
After searching the rest of the dependency tree exhaustively, these were the
goals I've had most trouble fulfilling: base, QuickCheck, splitmix, hadrian,
hadrian:selftest, ghc-platformGiving it high priority because it keeps blocking Marge. This job is not run on the quick validate so doesn't get tested that often.
