(ins)efraim@3900XT ~/workspace/guix$ time torsocks ./pre-inst-env guix build 
--no-grafts git-annex --target=aarch64-linux-gnu
guix build: error: gnu/packages/haskell-apps.scm:345:2: git-annex@8.20210903: 
build system `haskell' does not support cross builds

Interestingly it might be easier to get the haskell-build-system to
support cross compiling than to find the upstream blessed binary for one
of the GHC releases and use that as a bootstrap for later GHC releases
on aarch64.
