PyQt6 6.7.1 wheel: wrong manylinux glibc version?

Tue Jul 23 17:00:06 BST 2024

I think this is another case of using a too new Linux distribution to 
build the wheel (like the problem with PyQt5). PyQt-builder sets the 
manylinux version to 2.28 when it should really inspect the extension 
module for GLIBC symbols.  From memory 6.7.1 was built on Ubuntu 22.04 
and v6.7.0 on 20.04.

I'm in the process of moving from virtual machines to docker containers 
for the Linux builds so I should be able to confirm and correct this 
fairly easily.

Thanks,
Phil
