scan-build picks up the wrong compiler toolchain.

I have my Ubuntu machine configured with the alternatives set to Clang[++]. cc
is soft linked to Clang. c++ is soft linked to Clang++. And CMake is using
Clang[++]. Nonetheless, scan-build insists on loading GCC.

This happens with `scan-build cmake .`, in basic C/C++ projects.

This happens with `scan-build conan install -s compiler.cppstd=17 -s
compiler=clang -s compiler.version=10 --build missing .`, in C/C++ Conan
projects.

Example project:

Please fix scan-build so that it better respects the configured toolchain.
