configure.in (cpp_install_dir): Initialize from $enable_cpp if that's looking like a pathname.

        * configure.in (cpp_install_dir): Initialize from $enable_cpp
        if that's looking like a pathname.
        * configure: Rebuilt.
        * Makefile.in (install-cpp, uninstall-cpp): cpp_install_dir is an
        absolute pathname, not a $prefix relative pathname.
