Perl is always configured for AFS on RHEL9 and derivatives

[Grinnz]

Description
When building Perl on Rocky Linux 9, the "afs" configuration is always set to true, due to the root-level '/afs' directory always being present.

Ref: https://www.reddit.com/r/Fedora/comments/z090bw/whats_the_afs_dir_on_my_f37_system_its_empty/

Steps to Reproduce
Install Perl on RHEL/CentOS/Rocky Linux 9 or recent versions of Fedora Linux. The configure script will ask AFS-related questions and the 'afs' configuration will be set to true.

$ perl -V:afs
afs='true';

Expected behavior
Possibly there is some better way to detect if AFS is actually installed/in use? On CentOS 7:

$ perl -V:afs
afs='false';
