Thanks @analyticd I took a look. That specifically didn't work, but I made some changes that did work.

I'm running 64-bit Debian - arm64. I had to update the download package and install a few additional packages.

sudo apt install llvm-9 libncurses5 libnuma-dev 

wget http://downloads.haskell.org/~ghc/8.10.1/ghc-8.10.1-aarch64-deb9-linux.tar.xz
tar -xf ghc-8.10.1-aarch64-deb9-linux.tar.gz
cd ghc-8.10.1
./configure
sudo make install

libnurcses5 was discovered as a need during the make install command and libnuma-dev when trying to compile the Hello World application.

Now I just have ghc and ghci no cabal or stack by my very limited work in Haskell doesn't really need those. Maybe one day I'll do something complex enough in Haskell to need additional tooling.

I emailed the maintainer of GHC's ARM build (and that wiki page above) and he was kind enough to provide an updated URL for a pre-built cabal-install whose URL is referenced from here:

https://gitlab.haskell.org/ghc/homepage/-/commit/5076cb3b1672a99b07d891649114c434ff070475

To get the binary:
wget https://home.smart-cactus.org/~ben/ghc/cabal-install-3.4.0.0-rc4-armv7l-deb10.tar.xz
