    libstdc++47: Rework to prevent regeneration during install
    
    The installincludes target regenerated files such as c++config.h during
    the install phase.  It may be a minor bug as "bits/c++config.h:" would
    trigger it but "c++config.h:" without the subdirectory wouldn't.  In any
    case, generating it and two other headers to the local working bits
    directory wasn't necessary as installincludes target installs them in an
    accessible location.  Reworking the makefiles prevents a write operation
    during installworld.
