Recent platform linkers will no longer accept linking for a target
OS version less than 10.4. Recent SDKs no longer have the libgcc_s
shims used for 10.4 and 10.5. So we need to adjust tests that expect
these. Added some explanation too.
tested on darwin9, darwin16 and darwin18,
applied to mainline,
