Running automake with perl >= 5.22.0 produces the warning
Unescaped left brace in regex is deprecated, passed through in regex;
marked by <-- HERE in m/\${ <-- HERE ([^ \t=:+{}]+)}/ at
/ptx/work/dude/ejo/temptest/nodistro.0/sysroots/x86_64-oesdk-linux/usr/bin/automake
line 3936.
With perl-5.22.0 using a literal '{' in regexp is deprecated and should
be escaped.
This patch escapes the '{' characters to match in the regex of function
`substitute_ac_subst_variables_worker`.
