Comment:
 The upstream source tarball is repacked to drop off the regenerated material
 (mainly autotools related) and material provided by other packages (mainly
 autoconf-archive m4 files) to gain weight.
 (At the time of writing, the latest ax_prefix_config_h.m4 as distributed
 within the autoconf-archive is not compatible with the version distributed
 within Singular (serial 11); more precisely, not providing a prefix is an
 error in the lastest version (serial 15). Second, ax_python_with_version.m4
 does not belong to autoconf-archive.)
