I am not sure what the point is here. Are you unable to configure? or make all? or make check PETSc?
If so that should clearly be reported as a bug with all relevant information supplied. No, we have never and do not ever intend for PETSc users even developers to know or care about MACOSX_DEPLOYMENT_TARGET Anyways if you are reporting a bug and I am guess the bug correctly the fix is to add "was built for newer macOS version" to the list of filtered link warnings. There will be a bunch of such warnings that will need to be added to the filtering in the next few months but once they are in place the filtering should not be an issue.
