problems with PyQt5-5.15.0 linux wheel

Hello,

I=E2=80=99ve noticed something unusual about the =
PyQt5-5.15.0-5.15.0-cp35.cp36.cp37.cp38-abi3-manylinux2014_x86_64.whl =
wheel that is served by PyPi.

If you install it on Ubuntu 20.04 (py3.8) or Ubuntu 18.04(py3.6) it =
seems to be ok, but if you install it on Ubuntu 16.04 (py3.5) it does =
not install the Qt/plugin/ or Qt/translations/ folder like it does for =
the other Python versions.

This leads to runtime errors when you try to use PyQt5:

qt.qpa.plugin: Could not load the Qt platform plugin "xcb" in "" even =
though it was found.
This application failed to start because no Qt platform plugin could be =
initialized. Reinstalling the application may fix this problem.

I checked the PyQt5-5.14.2 wheel on Ubuntu 16.04 (py3.5) and it did =
install the plugins and translations, so this looks like a regression.

Regards,

Steve Borho=
