RFA: RL78: Add absolute symbol to RL78 linker scripts

[Nick Clifton <nickc at redhat dot com>]

Hi DJ,

  I recently committed a patch to the binutils to fix a problem with the
  evaluation of complex relocs for the RL78:

    https://sourceware.org/ml/binutils/2015-07/msg00286.html

  This patch requires that RL78 linker scripts PROVIDE a value for the
  symbol __rl78_abs__, so I would like permissions to apply the patch
  below to the scripts in libgloss.

  OK to apply ?

Cheers
  Nick
