Can gcc13 create fat binaries for Intel+ARM in one-liner?

The necessary parts Apple added (driverdriver.c) to enable that have not been updated since gcc-4.2, so one-pass universal is not available since then.
People occassionaly talk about updating driverdriver.c, and there are a few shell scripts floating around that do some of it, but that’s as far as it goes.

I also seem to recall that years later I tried a genuine (non-Apple) gcc, and creation of fat binaries as a one liner was no longer available.
