.tar.gz package(tarball) needs improvements

.tar.gz package is repeated for each distribution and version, only one tar.gz package is needed per architecture:

Red Hat Enterprise Linux / CentOS

maxscale-1.2.0-ppc64le-sles12_ppc64.tar.gz (POWER8 ppc64le)
SLES 11
maxscale-1.2.0-x86_64-sles11.tar.gz (x86-64)
maxscale-1.2.0-x86_64-sles11.rpm (x86-64)
Ubuntu
Ubuntu 14.04 LTS
maxscale-1.2.0-x86_64-ubuntu_trusty.deb (x86-64)
maxscale-1.2.0-x86_64-ubuntu_trusty.tar.gz (x86-64)
Ubuntu 12.04 LTS
maxscale-1.2.0-x86_64-ubuntu_precise.deb (x86-64)
maxscale-1.2.0-x86_64-ubuntu_precise.tar.gz (x86-64)
Debian
Debian 7
maxscale-1.2.0-x86_64-deb_wheezy.deb (x86-64)
maxscale-1.2.0-x86_64-deb_wheezy.tar.gz (x86-64)
Debian 6
maxscale-1.2.0-x86_64-deb_squeeze.deb (x86-64)
maxscale-1.2.0-x86_64-deb_squeeze.tar.gz (x86-64)

(from https://mariadb.com/my_portal/download/maxscale)

Moreover the tar.gz is missing etc folder and/or sample config files.
It does not look like a self contained, portable working version of MaxScale.
It would be good to make it such.
