OpenWrt automake patch

- Error
Unescaped left brace in regex is illegal here in regex; marked by <-- HERE in m/\${ <-- HERE ([^ \t=:+{}]+)}/ at ./bin/automake.tmp line 3938.


- Patch
tools/automake/patches$ cat 0002-port-to-perl-5.22-and-later.patch
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.
