This is temporary measure, as the problem cannot be solved cleanly right now.
The issue is that the msrv check uses the stable compiler, which uses a stable cargo. With a stable cargo, the unstable
build-stdoption is not respected within.cargo/config.toml. This meanscoreis never rebuilt with the atomic cfg flags so we get this error when building log version 0.4.19. The 0.4.19 release uses the atomic cfg flags instead of a custom build script, so by switching back to 0.4.18 we can avoid this issue... for now at least.
