Subject: [PATCH] bin/automake: escape '{' in regexp pattern
Based on perlre(1) documentation:
.. in Perl v5.26, literal uses of a curly bracket will be required
to be escaped, say by preceding them with a backslash ("\{" ) or
enclosing them within square brackets ("[{]") ..
References:
https://bugzilla.redhat.com/1239379
* bin/automake.in (substitute_ac_subst_variables): Escape the
occurrence of '{' character.
