Ticket details:
I looked at the debian freeciv package build failure at x32: https://buildd.debian.org/status/logs.php?pkg=freeciv&ver=2.6.6-1
The problem seems to be that Qt headers there both require pic, and disallow pie. Freeciv m4/qt5.m4 correctly detects the need to add -fPIC. I think -fPIE comes from debian build hardening.
I got the build go through all right by adding logic to qt5.m4 to try to disable pie in cases where it adds pic (but in such a way that there should be no regression for any builds that require pic, but cannot disable pie for some reason)
I'll attach the patch I used in that testing (for S2_6, but likely applies to S3_0 as is - likely not to later branches with qt6 support)
