Add v850 linker relaxation

[Nick Clifton]

Hi Guys,

  I am applying the attached patch which adds linker relaxation to the
  v850 toolchain.  It also removes the redundant references to the
  v850ea architecture.  The patch was developed a while ago and we now
  have permission to release it to the free software community.

Cheers
        Nick
