Mac M1 Linux aarch64 support

[peterglen]

I am running the ESP32 dev on Linux Ubuntu x86_64. Works fantastic. I installed Ubuntu on the new Mac book Air in a UTM virtual machine, and trying to compile ESP32 project(s). On installation, I encounter the message 'aarch(64)' is not supported. It would be nice to see this platform supported on the xtensa cross compiler (crosstool-NG) support. The M1 chip based platforms are awesome, here to get popular and stay. PS I tried to install the source ... difficult to compile; broken dependencies; Please help.

Hi peterglen,
We are going to release a toolchain for aarch64 (Linux) hosts soon, please go to https://github.com/espressif/esp-idf/issues/6432 and click "Subscribe" to get notified when the toolchain will be released.
We don't yet have plan for the native aarch64 macOS toolchain release (relevant Github issue: https://github.com/espressif/esp-idf/issues/6113) but for the time being the x64_64 macOS toolchain should get installed on M1 and should run fine (albeit slower) under Rosetta emulation.

Thank you; Look forward to it; I was able to compile the crosstool (after banging my head against the wall for two days) The actual solution was simple, minor corrections for the expat component configuration. Screenshot below.
