This requires having a cross compiler available (pkg gcc-aarch64-linux-gnu on debian). THis is in preperation for adding some amount of raspberry pi 4 support.

For reference, I tested this against my raspberry pi 4 using https://github.com/pftf/RPi4 + |

This is enough support that `pixiecore quick debian testing --arch arm64` is able to successfully boot a raspberry pi 4 that's using the experimental edk2 raspberry pi UEFI firmware. It does not seem to work with the built-in eeprom pxe booting the raspberry pi 4 includes, but the eeprom pxe implementation is severely lacking, so I'm not surprised.

This was tested with a raspberry pi 4 netbooted with the EDK2 UEFI pxe boot implementation. You can find prebuilt binaries for that over here: https://github.com/pftf/RPi4
Of note, this does not work with the raspberry pi eeprom's pxe implementation as best I can tell. I'm not actually convinced the eeprom pxe impl supports proxyDHCP at all since I wasn't even getting tftp or pxe traffic from it after sending the initial dhcp offer.
