Build broke as distributions now include Perl 5.26 and automake triggered an "Unescaped left brace in regex" error. Import upstream commit 13f00eb449 to fix that. Signed-off-by: Daniel Golle <daniel@makrotopia.org>

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.
