Duo Authentication Proxy on Raspberry Pi

In trying to install the duo auth proxy on a new Raspberry Pi 4 B+ running ubuntu server 20.04 LTS, I’ve run into an issue while building.

FIPS_text_start() returns NULL
make[2]: *** [../Makefile.shared:164: link_app.] Error 1
make[2]: Leaving directory '/home/ubuntu/openssl-1.0.2u/apps'
make[1]: *** [Makefile:157: openssl] Error 2
make[1]: Leaving directory '/home/ubuntu/openssl-1.0.2u/apps'
make: *** [Makefile:293: build_apps] Error 1

I can trace this back to this github issue, which seems to indicate lack of support for aarch64: https://github.com/openssl/openssl/issues/11105

Has anyone else had success or issues while trying to install the duo auth proxy on aarch64 / raspberry pi?
