`scripts/min-tool-version.sh` won't exist within the build dir if the 
option the user takes is "enter the kernel build directory", right? It 
only works if they use the `--path` argument in the `rustup override 
set` option.

I gave this a spin and works as expected, just thought I would mention 
this given how users sometimes simply copy/paste and this may be confusing.
