Now we have removed the m4 macros we had extracted from the autoconf-archive, and rely on either the host system having them pre-installed or for an installation script to install them by hand if necessary (such as seen here https://github.com/01org/cc-oci-runtime/blob/master/installation/rhel-setup.sh#L161), there are times during development when you'd just like to do that curl hand install 'by hand'. Thus, it would be good to extract that 'curl magic' into a separate script that can be both utilised by the install scripts as per above, or run by hand before a configure to get the relevant macros installed in place.
