Hum, it makes a difference locally but not so much according to the build-winetest job artifacts, I'm probably missing something here but I think it could mitigate the size increase from https://gitlab.winehq.org/wine/wine/-/merge_requests/6672 if doing this is acceptable.
We could probably use upx for the Gitlab CI, but I still think it would be nice to find a solution that doesn't require shipping the entire source.
(Actually it seems to be making a difference, but probably the incremental build didn't rebuild the test executables after the first commit here and they didn't get compressed. Another build here shows a 2x size gain https://gitlab.winehq.org/rbernon/wine/-/jobs/109725/artifacts/browse, even though that build here includes the changes from !6672, so all the test sources included)
