Here's a proposal for the intro.

  The table below shows various characteristics for all architectures
  supported by GCC.  It can be used to determine an appropriate variety
  of targets on which to test patches, and is also used by GCC
  maintainers to track of criteria that are considered when determining
  which targets to obsolete.
  
  Each characteristic has a unique letter.  Characteristics describing
  fundamental properties of the architecture or target use uppercase
  letters, and characteristics describing properties of the GCC port to
  that architecture use lowercase letters.  The appearance of a letter
  means that the architecture has that characteristic, a blank means it
  does not, and a question mark means the author didn't know whether the
  architecture had the characteristic or not.  For criteria used to
  determine whether an architecture should be obsoleted, the appearance
  of a letter is the desirable case and the lack of a letter is the
  undesirable case.
  
  Architectures are identified by the names of their subdirectories in
  gcc/config, not by the CPU fields that config.guess reports.
