I have attached the build environment difference between wine-staging 2.13 and 2.14. Since wine-staging 2.13 on the current system still works, the build environment is somewhat suspicious.
Did you try to rebuild an old Wine version with the new build tools? That would probably be a good test to make sure its really a build environment issue.
