libelf @0.8.13_2: checking build system type... configure: error: /bin/sh ./config.sub -apple-darwin21.2.0 failed

[NickFabry (Nick Fabry)]

While attempting to install qmk dependencies, in particular avrdude, avr-gcc and arm-none-eabi-gcc, the installs kept failing. Trying to trace down which dependency was failing led to libelf. I did a "sudo port clean libelf" to attempt a clean install, and libelf still failed to install:

I've attached the config.log and main.log files referenced above. In the config.log, this may have been the source of the error:

configure:5233: error: /bin/sh ./config.sub -apple-darwin21.2.0 failed

And in the main.log, this similar error:

:info:configure checking build system type... configure: error: /bin/sh ./config.sub -apple-darwin21.2.0 failed

I'm running macOS 12.1, XCode 13.2.1 (13C100). Thanks for your volunteerism and work.

So it needs newer config.guess/config.sub to recognize Apple Silicon systems.
