      Scope:

      Support gcc 4.8.5 and build in Evergreen

      • Fix build with gcc 4.8.5
      • Add tasks to build in Evergreen with gcc 4.8.5.

      Background & Motivation:

      Building C++ driver r3.10.1 with gcc 4.8.5 results in compiler errors:

      /root/mongo-cxx-driver/src/bsoncxx/include/bsoncxx/v_noabi/bsoncxx/stdx/string_view.hpp:571:45: error: redeclaration 'bsoncxx::v_noabi::stdx::basic_string_view<Char, Traits>::npos' differs in 'constexpr'
const std::size_t basic_string_view<C, Tr>::npos;
                                            ^
/root/mongo-cxx-driver/src/bsoncxx/include/bsoncxx/v_noabi/bsoncxx/stdx/string_view.hpp:136:32: error: from previous declaration 'bsoncxx::v_noabi::stdx::basic_string_view<Char, Traits>::npos'
    static constexpr size_type npos = static_cast<size_type>(-1);

      /root/mongo-cxx-driver/src/bsoncxx/include/bsoncxx/v_noabi/bsoncxx/json.hpp:83:42: error: missing space between '""' and suffix identifier
BSONCXX_API document::value BSONCXX_CALL operator""_bson(const char* json, size_t len);

      Errors were produced on the rhel-70-large host on Evergreen.

      Support for gcc 4.8.5 is requested to support building with the gcc on RHEL 7.9. See slack thread.

      This patch appears to fix the build for r3.10.1: https://gist.github.com/kevinAlbs/1bd5cac64285a693efb054b11600ebe7
