Don't expose bignum backend in ghc --info (#20495)
ghc-bignum
will become reinstallable (potentially with different backends) and GHC itself is backend agnostic. So don't expose bignum backend with ghc --info
(which can be wrong, cf #20495 (closed)) but expose it with GHC.Num.Backend.backendName
.
Querying the backend can now easily be done with:
❯ _build/stage1/bin/ghc -e "GHC.Num.Backend.backendName"
"native"
