Probe for options required to enable C++11 support

At this point it seems reasonable to assume the C++ compiler can
support C++11 (Debian wheezy and Ubuntu trusty both have a recent
enough GCC), so we just need to probe for any options required to
enable this.

Fixes building 1.2.31 with GCC < 6, reported by Wookey.
