kbuild: do not drop -I without parameter
Linux commit 48f6e3cf5bc6dd0ee00405342ff310c3b1fedb35 [ Adjusted for barebox for some missing commits ] 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. Signed-off-by: Masahiro Yamada <> Signed-off-by: Sascha Hauer <>
