Darwin: Use -platform_version when available [PR110624].
Later versions of the static linker support a more flexible flag to
describe the OS, OS version and SDK used to build the code. This
replaces the functionality of '-mmacosx_version_min' (which is now
deprecated, leading to the diagnostic described in the PR).
We now use the platform_version flag when available which avoids the
diagnostic.

* config/darwin.h (DARWIN_PLATFORM_ID): New.
(LINK_COMMAND_A): Use DARWIN_PLATFORM_ID to pass OS, OS version
and SDK data to the static linker.
