configury: automake 1.12 as deprecated automatic de-ANSI-fication support
Fix this issue with automake 1.12:
| configure.ac:23: error: automatic de-ANSI-fication support has been removed
[fche:] Note that the systemtap git repository and source releases include
autoconf- and automake-generated files, so this is only an issue for those
who have an unusual reason to regenerate them.
