Looks like building 32-bit arm on Mac-arm64 isn't supported. Feel free to figure out what it would take to make it work. Does MacOS even support executing 32-bit arm binaries? If yes, then probably the changes are rather straightforward. If not, then the only thing V8 could do (which hasn't been done before and is likely difficult) would be to allow simulator builds of 32-bit architectures in 64-bit binaries. Lacking that, you could set up a VM, or install (some "multilib"-capable distro of) Linux on your MacBook, or get a 32-bit arm device (like a Raspberry Pi).
(FWIW, when I tried gm arm.release, I got the correct target_cpu = "arm" automatically, so that at least works.)
