[Buildroot] [git commit] autoconf: don't try to build Emacs files

[Peter Korsgaard]

commit: http://git.buildroot.net/buildroot/commit/?id=d2be9be63d2b1120c4ec0c3c445075a7311ef523
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master

When building autoconf for the target, we already passed EMACS="no" to
prevent autoconf from building Emacs mode files. But we weren't doing
that when building autoconf for the host. This causes problems when
'emacs' is not really emacs, but a sort of clone like Jove. So we also
pass EMACS="no" when building host-autoconf to avoid autoconf
./configure script from detecting emacs and then use it to build .elc
files from .el source code.
