[issue42701] Discrepency between configure.ac and configure

[Michael Felt]

Michael Felt <aixtools at felt.demon.nl> added the comment:

This is beginning to look like it is an issue with the version of automake installed: 

aixtools at gcc119:[/home/aixtools/cpython/cpython-master]automake --version
Unescaped left brace in regex is deprecated, passed through in regex; marked by <-- HERE in m/\${ <-- HERE ([^ \t=:+{}]+)}/ at /usr/bin/automake line 3936.

Will test on a system where I can install the latest automake.

Assuming an updated version of automake fixes that - but not knowing autotools well enough - is there a simple addition to ensure that automake-1.16 is used?
