      When using the build invocation: 

      python3.8 buildscripts/scons.py --variables-files=etc/scons/mongodbtoolchain_stable_clang.vars --gcov

      The build will fail with this error:

      Checking if C compiler is clang 7.0 (or Apple XCode 10.2) or newer...no
Checking if C++ compiler is clang 7.0 (or Apple XCode 10.2) or newer...no
ERROR: Refusing to build with compiler that does not meet requirements
See /home/ubuntu/mongo/build/scons/config.log for details

      The build could check if the gcov option is being used with clang, and report that clang and --gcov is not currently supported, and alternatively use --gcov with gcc instead.
