This one line change truncates garbage from the end of the ARDUINO definition
In the arguments to g++ previously there has been a definition in the format of
-DARDUINO=10819
The contents of the file where this is read from has changed and contains non-numeric additions.
Some esp8266 code makes the assumption that ARDUINO will be numeric. This change removed the new extra information
The value of ARDUINO changes from '108019+dfsg1-1' back to 108019.
