official find_sdk verify

When doing an official build, don't bail out if Xcode doesn't know about the
SDK to verify when an SDK path is set. The SDK path supersedes whatever
find_sdk is supposed to find.

Also: Reorganize the SDK and deployment target variables to be scoped more
appropriately. Add a mac_sdk_min variable to set the main argument to
find_sdk.

it skips the warning at the end if best != min.  but there is no check to make
sure the sdk_path actually exists.  Is that what you want?

I think that’s fine. The build will die very quickly in that case and it should
be obvious why by the compiler’s inability to include standard headers.
