it fails on a HP ARM-based Chromebook Linux with the following console output:

system reports the aarch64:

$ uname -a

it does actually work fine if debugger.lua is updated to something like:

        local function detect_linux()
            if shell "uname -m" == "aarch64" then
                PLATFORM = "linux-arm64"
            else
                PLATFORM = "linux-x64"
            end
        end

ok, created PR for it. I didn't add more testing logic for other architectures/platforms.
