Re: libxkbcommon version-script detection

Hi Dimitry,

Yes it is stable/14 from a week ago. It is from within a jail, but I just tested it outside the jail and it fails as well.

The jail environment has been freshly rebuild on Januari 8. All executables and binaries are completely recompiled.

Same problem on another older stable/14 system.
