v850 ld failure for v850-rtems on master

[Nick Clifton]

Hi Pedro,

  Your recent patch to change the architecture names for the V850 has 
  caused a problem for people using custom V850 linker scripts:

https://sourceware.org/ml/binutils/2016-03/msg00263.html

  Changing the OUTPUT_ARCH name in the script does work, but the change 
  is not backwards compatible.  Would a patch like this, to add an extra
  entry with the old architecture name, cause problems for GDB ?

  Your original posting talked about spaces in the architecture name
  causing problems, but this patch does not reintroduce any spaces, so
  maybe it will work ?

Cheers
