[Buildroot] [git commit] bison: add host-m4 as dependency

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=7b6f4d49a99f6c8edb5286e52f2cc54f7094d5d2
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

Pull in host-m4 as dependency since it requires a new-enough m4 to build
properly and some distributions don't update that often. Fixes:
