[patch] cr16-elf target: discard linkonce sections

[M R Swami Reddy]

Hi,
Below patch included in elf32-cr16.c:elf32_cr16_relocate_section to 
discard the linkonce sections:
Ran "make check-gas", "make check-binutils" and make check-ld". No 
regression and 2 linkonce tests
passed from ld test suite. Is it ok for check-in?

ChangeLog:
    M R Swami Reddy <MR.Swami.Reddy@nsc.com>

       * elf32-cr16.c (elf32_cr16_relocate_section): Add code to discard the
       linkonce or linker script discarded section.

Approved - although since this is a patch to a CR16 specific file and 
you are the maintainer you do not really need to seek approval.

Cheers
