Using VSCode with nRF Connect extension on Ubuntu Linux 22/04 with nRF SDK 3.0.1 and nRF Toolchain 3.0.1 installed
I can create a build configuration for Zephyr's hello_world sample app to build for the native_sim board and build without any issue but the IDE extension keeps asking for a pristine build afterwards despite no build errors being reported. In the VSCode output console (where extensions print log info) it keeps on printing "Unable to find the toolchain at path: /usr/bin/gcc" like this.
The problem is that since the extension is not convinced that the project was built it hides all action buttons. All I get is this:

so it becomes impossible to debug/run without having to resort to custom launch commands or manually configuring gdb which defeats the purpose of using the extension in the first place.
