testsuite, Darwin: Fix darwin-comm-1.c error messages for Darwin <= 10.

Browse source 
When amending the allowed alignment size to accommodate the larger values
permitted by newer tools, we retained the object file limit of 2^15 for
Darwin versions <= 10, since that is what the native tools expect there.

This triggers a different diagnostic path with a distinct error message,
which is checked in the revised test here.
