The https://github.com/stevegrubb/distro-elf-inspector/blob/main/bin/distro-features/aslr/Makefile defines a bunch of PIE-related compiler parameters. However, if this is focused on the distro functionality, checking the behaviour with the compiler parameters defined by the distros might be more relevant.
I'm thinking about something like

PASSES=1024but I'd like to hear about other potential ways of using the values configured via redhat-rpm-config.
The README says
2) run ./test-system (install dependencies if missing)
but that fails with
# ./test-system
-bash: ./test-system: No such file or directory
The file test-sytem likely needs to be renamed.
