Log Message:
Update to 1.6.2

Upstream no longer builds documentation by default.  Don't enable it,
because then the build fails because it assumes mapnik is present.

Note that C++11 is now required by upstream, at least if mapnik is
included.  For now, just add C++ to languages.

Add patch to remediate new bashisms.
