Retrying a CentOS build alongside trial-and-error builds with minimal Ubuntu 
environment
My current minimal ubuntu-based build is running the base dockerized 
ubuntu:xenial image extended with
        g++-multilib  \
        git  \
        ca-certificates  \
        zip  \
        unzip  \
        make  \
        python  \
        file  \
        xz-utils  \
        gettext  \
        curl  \
        p7zip-full  \
        texlive-xetex \

might still need more packages before it’s up and running

The ubuntu minimal environment builds alread led to a couple of updates in my 
gub fork (https://github.com/aikebah/gub) for URLs that are wget-able, but not 
curl-able as curl is not following the http 301 moved permanently redirects (at 
least python.org and freedesktop.org …. new minimal ubuntu build running to see 
if more packages fail the bootstrap when only curl is available.

once I pass the gub bootstrap I’ll create a pull-request for the URL updates
