    config: don't hardcode toolchain binaries
    
    Currently the names of the build toolchain binaries are hardcoded in
    StdGNU.mk, and the values from the environment are ignored.
    
    Switch StdGNU.mk to use '?=' instead of '=', so that values from the
    environment are used if present, else default to the values provided
    by the config file.
    
    This change fixes the gitlab CI loop, that was relying on passing
    custom values in the environment variables for the compiler and the
    linker.
