9.0.1-rc1 build panics on Fedora armv7

Summary

I haven't been able to investigate yet but on Fedora armv7hl ghc is panicking in the middle of building 9.0.1-rc1, for Fedora 32, 33, and Rawhide.

Steps to reproduce

The srpm is temporarily available from https://kojipkgs.fedoraproject.org//work/tasks/4616/58904616/ghc-9.0.0.20201227-97.module_f33%2B10901%2B88a8c7b4.src.rpm or can be generated from https://src.fedoraproject.org/rpms/ghc/tree/9.0 (commit 2e7b080e)

Gives https://kojipkgs.fedoraproject.org//work/tasks/4887/58904887/build.log [3.6MB,temporary link]:
