If a toolchain is configured with `DEFAULT_SYSROOT`, then this could result in an unintended value for `-syslibroot` being passed to the linker if the user manually sets `-isysroot` or `SDKROOT`. Let's fix this by prioritising command line flags when determining `-syslibroot` before checking `getSysRoot`.
