[PATCH RFC] common: env: handle var="" not as var=NULL

2016-06-13 Thread Alexander Aring

This patch changes the behaviour which I think is used everywhere in barebox code. Currently var="" and var=NULL will end in the same behaviour. New behaviour is: setenv(name, "")-> sets name to "" \-> getenv(name)-> "" setenv(name, NULL) -> deletes env \-> getenv(name)
