[Bug preprocessor/33305] We should warn about empty macro arguments

[manu at gcc dot gnu dot org]

There was talking about creating a -Wundefined flag that warns about undefined
behaviour (PR30334). Would this fit in there? (-pedantic is not supposed to
warn about undefined constructions as far as I know).
