[Resend] RFA: Add support for RX architecture.

[Nick Clifton]

Hi Jeff,

  This is a resend of a post from yesterday which failed because it
  was too big.

  I would permission please to apply the attached patch which adds
  support for the RX architecture to the newlib (and libgloss)
  sources.

  I have left off the tarball of the new files this time, in order to
  keep the email down to a reasonable size.  They are just some
  assembler source files for the libc memory and string functions and
  the libgloss board functions.

  OK to apply ?

Cheers
  Nick
