[Buildroot] [git commit branch/2018.08.x] package/dante: needs autoreconf

[Peter Korsgaard]

commit: https://git.buildroot.net/buildroot/commit/?id=094ffdfdb598785296d50a37e07493d406db1c62
branch: https://git.buildroot.net/buildroot/commit/?id=refs/heads/2018.08.x

We have a patch that touches a .m4 file, so we need to regenerate the
configure script. Otherwise, this is done during the build step, and
some environment variables are thus missing and the build may fail when
the host machine does not have the expected autostuff tools.

Fixes:
