Toolchain is missed for aarch64

I tried to compile program for esp32 on aarch64 environment (Ubuntu 18.04.3 64bit on Raspberry Pi 3B+) but it was failed for not found tool chain.

Error log:

I found a similar problem on issue thread of esphome( https://github.com/esphome/issues/issues/594 ) and a solution on the thread solved my problem. I replaced tool chain like this.

mv ~/.platformio/packages/toolchain-xtensa32 /tmp
curl -sSL -o ./toolchain-xtensa32.tar.gz https://github.com/esphome/esphome-docker-base/releases/download/v1.4.0/toolchain-xtensa32.tar.gz
tar -xzvf ./toolchain-xtensa32.tar.gz -C /home/${USER}/.platformio/packages/
rm ./toolchain-xtensa32.tar.gz

The difference of package.json of each tool chain was number of system.

package.json of new toolchain

{
    "description": "GCC for SoC Xtensa L108",
    "name": "toolchain-xtensa32",
    "system": [
        "linux_aarch64"
    ],
    "url": "https://github.com/espressif/esp-idf",
    "version": "2.50200.80"
}

package.json of old replaced toolchain

{
    "description": "GCC for SoC Xtensa L108",
    "name": "toolchain-xtensa32",
    "system": [
        "linux_armv7l",
        "linux_armv8l",
        "linux_aarch64"
    ],
    "url": "https://github.com/espressif/esp-idf",
    "version": "2.50200.80"
}

Is it possible to download tool chain only for aaruch64 on aarch64 environment to prevent the error about “not found”?

Thank you.

the link for download is dead. Have you an other ? Please make a new version to make the instal in aarch64 easier !
