bitbake only checks whether it equals "1" or not. Without this patch, an empty
string is the same as not set since it doesn't equal to "1". But if it is
set to "0", bitbake uses it as enable network, sanity.bbclass uses it
as disable netowrk, which are conflicted. We can add checking for empty string,
but do we have to ? Limit it to "0" or "1" makes things clear.
