svn diff for Unbound fixing LibreSSL issue

This patch is partly an upstream fix https://www.nlnetlabs.nl/bugs-script/show_bug.cgi?id=694

In addition
  - Adds USES+= autoreconf
  - Silences portlint -AC
  - Adds regression-test target

the files/patch-configure.ac can be removed when the next version is released as it is included upstream.

Using the patch and with LibreSSL installed the make regression-test target shows all OK.
Comment 3 Sergey Matveychuk freebsd_committer 2015-08-19 15:10:27 UTC
This is a good patch. But does it fix the sigfault?
