Dirk, can you clarify where the flags come from? The current CRAN builds (big-sur-x86_64 and big-sur-arm64) use
export SDKROOT=/Library/Developer/CommandLineTools/SDKs/MacOSX11.sdk export MACOSX_DEPLOYMENT_TARGET=11.0 so the lowest target is 11.0 and it is no longer forced it in the flags (so that users can more easily choose their desired targets).
