Adam Duskett 22dbe0035f automake: fix unescaped left brace warning patch
Automake currently has a unescaped left brace in it's automake.in folder
that generates the warning:
"Unescaped left brace in regex is deprecated, passed through in regex;"
This patch, which is backported from upstream fixes this warning.

Subject: [PATCH] automake: port to Perl 5.22 and later
Without this change, Perl 5.22 complains "Unescaped left brace in
regex is deprecated" and this is planned to become a hard error in
Perl 5.26. See:
http://search.cpan.org/dist/perl-5.22.0/pod/perldelta.pod#A_literal_%22{%22_should_now_be_escaped_in_a_pattern
* bin/automake.in (substitute_ac_subst_variables): Escape left brace.
