[boost] [testing] Lots of spurious test runners

There are rather a lot of test runners that fail all tests due to setup errors: sandia-gcc-5.4.0-c++11     cc1plus: error: unrecognized command line option "-std=c++11" sandia-gcc-5.4.0-c++14     cc1plus: error: unrecognized command line option "-std=c++14" sandia-gcc-6.4.0-c++11     cc1plus: error: unrecognized command line option "-std=c++11" sandia-gcc-6.4.0-c++14     cc1plus: error: unrecognized command line option "-std=c++14" sandia-intel-16.0-c++11    /bin/sh: line 1: icpc: command not found sandia-intel-16.0-c++14    /bin/sh: line 1: icpc: command not found sandia-intel-16.0    /bin/sh: line 1: icpc: command not found sandia-intel-17.0-c++11    /bin/sh: line 1: icpc: command not found sandia-intel-17.0-c++14    /bin/sh: line 1: icpc: command not found sandia-intel-17.0    /bin/sh: line 1: icpc: command not found teeks99-02-dc3.1-11-Docker-64on64 /usr/bin/../lib/gcc/x86_64-linux-gnu/4.8/../../../../include/c++/4.8/functional:2194:2: error: no type named 'type' in 'std::enable_if'  (and more errors from <functional> - the compiler appears to be unable to handle the std lib headers so I'm not sure what the point of testing it is?) igaztanaga-develop-gcc-3.4c++03      cc1plus.exe: error: unrecognized command line option "-fvisibility-inlines-hidden" cc1plus.exe: error: unrecognized command line option "-fvisibility=hidden" Best, John. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
