Fix linux build

[micheldebree]

What changed?

Linux build succeeds

But when I do make ubuntu (Docker build), after compilation I get

strip artifacts/SIDFactoryII
mv artifacts/SIDFactoryII artifacts/SIDFactoryII_LINUX_2026-03-13.efcd038
mkdir -p artifacts/SIDFactoryII_LINUX_2026-03-13.efcd038/config
mv artifacts/drivers artifacts/SIDFactoryII_LINUX_2026-03-13.efcd038
mv: inter-device move failed: 'artifacts/drivers' to 'artifacts/SIDFactoryII_LINUX_2026-03-13.efcd038/drivers'; unable to remove target: Directory not empty
make: *** [Makefile:106: dist] Error 1
make: *** [ubuntu] Error 2

This only occurs in the local docker build, which is only for testing purposes. Merging because the master build is now broken
