cargo fails to build on Mac OS Big Sur

[pacu]

We were reported that there are issues with the rust welding build and Mac OS X Big Sur.
Main issue being: note: ld: library not found for -lSystem
Due to the amount of user complaints about its stability we are currently not supporting that particular version of Mac OS X for now.

We encourage all of our users and contributors to document the problem under this issue and send PRs with possible solutions.
