    cmake: fix compiling some C++ projects with Yocto SDK and GCC
    
    Setting CMAKE_SYSROOT in the toolchain file allows CMake to correctly
    remove user-provided system include directories pointing to
    <sysroot>/usr/include. The mentioned projects failed with "stdlib.h:
    No such file or directory #include_next <stdlib.h>".
