PySide2: 64bit builds fail but 32bit builds succeed (Clang issue?)

[Richard Shaw]

I'm working on getting PySide2 into Fedora which gives you python bindings
for Qt5.

It uses some code specific to Clang so I can't use gcc. I've got everything
building but for some reason the 64bit builds fail for two binaries which
rpmbuild can't link back to build-ids.

BUILDSTDERR: error: Missing build-id in
/builddir/build/BUILDROOT/python-pyside2-5.12.1-1.fc31.x86_64/usr/lib64/python3.7/site-packages/PySide2/pyside2-lupdate
BUILDSTDERR: error: Missing build-id in
/builddir/build/BUILDROOT/python-pyside2-5.12.1-1.fc31.x86_64/usr/lib64/python3.7/site-packages/PySide2/pyside2-rcc

As far as I can tell -g is being passed to clang for these binaries...

But the 32bit builds complete. I'm pretty much at a loss at this point and
it's difficult to troubleshoot because I can't build locally. Mock even
with --enablerepo=local is (was?) missing gcc-9.0.1. (no more mirrors to
try).
