BUG: Visual Code on RaspberryPI errors


I’ve installed successfully lthe atest Visual Code onto my Raspi4:
Linux raspi4 4.19.97-v8+ #1294 SMP PREEMPT Thu Jan 30 13:27:08 GMT 2020 aarch64 GNU/Linux
(I had to switch the x64-kernel mode to 1 in the config.txt, as the VC is x64 in the latest releases)

VC runs perfectly smooth - but PlatformIO IDE plugin is not.

Right from the start (while installing and then later after every VC restart), there is an error notification:
Architecture arm is not supported.

Later, the build process is not running:
avr-gcc-ar: Cannot find plugin ‘liblto_plugin.so’
avr-g++: error trying to exec ‘cc1plus’: execvp: No such file or directory

I’ve tried to switch the build-chain from the IDE to the CLI:
platformio-ide.useBuiltinPIOCore: false

But as the CLI version of pio is not working as well (another issue I’ve posted into the CLI forum), I’m stocked.

Is it please possible to run the Visual Code IDE plugin under Raspi? When VC is running perfectly, it’s a PITA that the pio is not.

Thank you
