German,
This is easier than you think. Just remove the $(shell ... ) from around
your shell call and add the call to a target like this:
check_code:
/path/to/my/script.sh
Then put the check_code target in your dependency graph somewhere.
Scripts return values to the shell. If you call these as commands
instead of having the make $(shell) macro invoke them, the exit code
becomes the command status to make.
