[BUG] Cannot compile for ststm32 on RPi 3B (toolchain unavailable)

[rmeno12]

Did you test the latest bugfix-2.0.x code?

Yes, and the problem still exists.

Bug Description

I'm trying to compile Marlin for a BigTreeTech SKR 2 on a Raspberry Pi 3 Model B Rev 1.2. PlatformIO is unable to find the gcc toolchain corresponding to ststm32@~12.1.

I am able to find references online that using ststm32@~15.2 should provide a compatible version of the toolchain, but simply making that change in ini/stm32-common.ini didn't help.

Bug Timeline

Error from PlatformIO being unable to find the version of gccarmnoneabi for the RPi's architecture. Error is Error: Could not find the package with 'platformio/toolchain-gccarmnoneeabi @ ~1.90201.0' requirements for your system 'linux_aarch64'. Full output included below.

Steps to Reproduce

1. clone Marlin on the bugfix-2.0.x branch
2. change the default_envs variable in platformio.ini to BIGTREE_SKR_2
3. run pio run
