[PATCH] gas: make S_IS_LOCAL() and S_IS_EXTERNAL() exclusive of one another

[Jan Beulich]

While they aren't opposites of each other, there also shouldn't be any
symbol for which both return true; both may return false. Therefore
use S_IS_EXTERNAL() in S_IS_LOCAL(), thus subsuming the sanity check
which so far both did alike.
