I tried building ejabberd in a minmal config, with:

    BR2_x86_i686=y
    BR2_TOOLCHAIN_EXTERNAL=y
    BR2_INIT_NONE=y
    # BR2_PACKAGE_BUSYBOX is not set
    BR2_PACKAGE_EJABBERD=y
    # BR2_TARGET_ROOTFS_TAR is not set

And it fails at build time, with a lengthy error message, that I do not
completely grasp:

    /home/ymorin/dev/buildroot/O/host/usr/lib/erlang/bin/escript rebar
get-deps && :> deps/.got
    ==> rel (get-deps)
