      Some architectures need to set options in the file configparms.
      This is the case for sh3/4, which really need to set configparms as of
      gcc-3.4/glibc-2.3.2.

      Unless you are building a toolchain for sh3/4, you should leave that empty.

      Note: this is awkward, doesn't work well if you need more than one
            line in configparms

config LIBC_GLIBC_USE_PORTS

      The ports addon contains some architecture ports that are not available
      in the official glibc distribution.
      
      For example, this is the case for ARM with glibc >= 2.4
      
      Say n only if you're sure that your architecture is in the official
      glibc distribution for your chosen version.

    help
      Extra addons to include in glibc.
      
      Eg.: crypt        (for very old glibces)
           linuxthreads (for the linuxthreads implementation of threads)
