Die gracefully

Browse Source 
Don't explode into a 20 line stack trace if the kll file is formatted
incorrectly. Instead simply show the error message and exit with an
error code (which will stop the rest of a make command).

A misformatted file is most likely a user error so showing the full
backtrace for debugging is not necessary. The file and line number
should (hopefully) be enough to fix the parsing error.
