autotools: emit error message when autoconf-archive is missing

Forbid the AX_COMPARE_VERSION macro from being found in the output
configure script. If autoconf-archive is not installed when autoreconf
is run, the following error message is emitted:

configure.ac:231: error: possibly undefined macro: AX_COMPARE_VERSION
      If this token and others are legitimate, please use m4_pattern_allow.
      See the Autoconf documentation.
autoreconf: /usr/bin/autoconf failed with exit status: 1
