fix LTO on MacOS

Browse Source 
If no `-minimum-os-version` is given, ignore the `override-module`
warnings. The user not using, `-minimum-os-version` opts you into linker
warnings about target versions.

If a `-minimum-os-version` is provided, normalize it to a full version
`11` to `11.0.0` for example. The linker seems to want that when doing
LTO.
