Ejabberd available as a buildroot package

Johan Oudinet contributed a new ejabberd package in buildroot
sponsored by Green Communications.

Buildroot can generate any or all of a cross-compilation toolchain, a root filesystem, a kernel image and a boot loader image. The generated root filesystem contains a libc (uClibc, glib, eglibc or musl), busybox and some extra packages. Now buildroot allows to include Erlang and ejabberd in the generated root filesystem.

This makes very easy to build a custom and robust xmpp server for your embedded hardware, router or appliance, as buildroot is designed with simplicity in mind.
