Fix the following build failure raised since bump of autoconf to version
2.71 in commit ecd54b65c1f998a7ccd91f7c523e4ff38c4781da:
autoreconf: error: cannot create config/autoconf: No such file or
directory
Indeed, the config/autoconf directory does not exist, and therefore
the AC_CONFIG_AUX_DIR invocation serves no purpose.
Fixes:
