ghcWithPackages: list missing targets with NCG available

Browse Source 
Based on https://gitlab.haskell.org/ghc/ghc/-/wikis/platforms, although
it sadly doesn't list when the backends were introduced.

* PowerPC, x86 (and x86_64) and Sparc have been supported for longer.

* aarch64-darwin is new in 9.2.1 and backported to 8.10.5, 8.10.6 and
  8.10.7 (check is dumb here since we'll grep for 8.10.7 anyways when
  upgrading)

Fixes ghcWithPackages failing to evaluate on aarch64-darwin because of
missing support for the platform in LLVM 9's compiler-rt.
