Comment (by jmroot):

 That's still quite strange, since the `-arch arm64` option should make
 clang build for arm64 regardless of what architecture the program itself
 is running as. I guess you have your fix, and running natively is
 certainly preferable anyway, but please feel free to reopen if anyone
 figures out more about this and knows how we can prevent such problems
 when running via Rosetta.
