MN10330: Do not use linker relaxation and incremental linking together

Hi Guys,

  With the MN10300, enabling linker relaxation when performing a
  incremental link does not work:

    % mn10300-elf-gcc hello.c -mrelax -r
    collect-ld: --relax and -r may not be used together
    collect2: error: ld returned 1 exit status

  Hence I am applying the patch below as an obvious fix for the problem.
  Tested without regressions on an mn10300-elf toolchain.

Cheers
  Nick
