Subject: [PATCH] configure: Remove obsolete check for -b i486-linuxaout

If there are still a.out system arounds, they shouldn't need this
anymore because the toolchain has been fixed.

* configure.ac (emacs_cv_b_link): Remove obsolete check.

(cherry picked from commit 6c1413d5ef0d1fea639b0d8c83a0c0065d99359b)
