    elf: ldconfig should skip temporary files created by package managers
    
    This avoids crashes due to partially written files, after a package
    update is interrupted.

I can't judge but looks like something wrong make in steam client because all other software is not affected by this change.

Downstream bug report: https://bugzilla.redhat.com/show_bug.cgi?id=2248915

Steps for reproducing this issue:

1. Update glibc to 2.38.9000-18.fc40 version
2. a) Launch any Window game in Steam client with Proton compatibility layer.
   b) Or launch native Linux game in Steam client with "Steam Linux Runtime 1.0 (scount)"
