bpo-43568: Drop support for MACOSX_DEPLOYMENT_TARGET < 10.3 (GH-25827)
Only complain if the config target is >= 10.3 and the current target is < 10.3. The check was originally added to ensure that incompatible LDSHARED flags are not used, because -undefined dynamic_lookup is used when building for 10.3 and later, and is not supported on older OS versions. Apart from that, there should be no problem in general with using an older target. Authored-by: Joshua Root <jmr@macports.org>
