kbuild: do not drop -I without parameter
The comment line for addtree says "skip if -I has no parameter".
What it actually does is "drop if -I has no parameter". For example,
if you have the compiler flag '-I foo' (a space between), it will be
converted to 'foo'. This completely changes the meaning.
What we want is, "do nothing" for -I without parameter so that
'-I foo' is kept as-is.
