arm64 (and PowerPC...) builds were re-enabled in [ce28396921980998935ee1b3025fbb42a75ae328/macports-ports] and [3de9eefec887788181c3197208c6bd9f487a3934/macports-ports] by forcing macOS 11 deployment target; apparently macOS 12 deployment target and later is what complains about these unaligned pointers.
Here's how another project fixed it though: https://github.com/RfidResearchGroup/proxmark3/issues/1485#issuecomment-982089666

all this makes me wonder if forcing the deployment target to 11 to allow this to pass through the linker is actually doing the right thing, or is it just getting past the warnings/errors but emitting broken code?
