    [CMAKE] Unify configs for architectures
    
    config*.cmake files are constantly getting out of sync between
    each other. Besides that, the parameters are not really dependent
    on a target architecture, but rather on a compiler (except *ARCH)
    
    This approach seems to be more future-prone, and allows to see
    all the options in one file (there are really not that many of them)
