  o Minor features (build):
    - When building on a system without runtime support for some of the
      runtime hardening options, try to log a useful warning at configuration
      time, rather than an incomprehensible warning at link time.
      If expensive hardening was requested, this warning becomes an error.
      Closes ticket 18895.
Check linking of hardening options, give better warnings if it fails. Previously we'd only check whether the hardening options succeeded at the compile step. Now we'll try to link with them too, and tell the user in advance if something seems likely to go wrong. Closes ticket 18895. 2016-05-16 15:37:27 +02:00			`o Minor features (build):`
