Subject: [PATCH] haskell.compiler.ghcHEAD: 9.5.20220921 -> 9.7.20221224

Finally building a cross compiler using hadrian is possible, but there
are some outstanding issues regarding external libraries in the package
db which causes issues with ghc-bignum.

-  hadrian doesn't support building an installable GHC cross-compiler at the moment.
-  Consider using GHC 9.4 or lower which support this via the make build system.
