bufferutils now builds a universal binary. This does not work on older macOS (like Mojave) as the compiler does not support -arch arm64, but also breaks on newer macOS as we pass arch-specific flags such as -march as CFLAGS in the test environment.

Bit odd:

ZlibError: zlib: incorrect data check

I'm guessing this is revealing something already broken. The difference with older node is that we aren't using our zlib (or rather the system's on macOS) - we should fix that.

I removed the failing test from node@14 in #86046 to avoid delaying the version update for a problem in our testing environment.

Node 16 fix bundled in with #86291.
Node 14 fixed in #86512.
Node 12 fixed in #86526.
