Multiple tests failing when building RPMs on aarch64 fedora

I am packaging STEPCode for Fedora. The system builds fine* for x86_64, but there are multiple self-test failures on aarch64, which is a relevant architecture option.

(https://download.copr.fedorainfracloud.org/results/mumble07/stepcode/fedora-rawhide-aarch64/10251740-stepcode/builder-live.log.gz)

These look to be major functionality errors, so I don't want to suppress them.

*hardcoded install directories are a pain, but I found a workaround.
