While still waiting for CI results (BAT results don't cover the new subtest) 
I've collected results from a forced execution of the subtest in BAT scope on 
trybot: https://patchwork.freedesktop.org/series/113608/#rev2

While working as expected on most platforms, the test failed on some ancient 
ones instead of skipping.  I've fixed this issue and tested the fix 
successfully on trybot: https://patchwork.freedesktop.org/series/113608/#rev3

I'm still waiting for your comments, if any, before I submit the fixed 
version.

Thanks,
Janusz
