* elf-m10300.c (mn10300_elf_relax_section): Extend previous fix to cover forward jumps.

* ld-mn10300/i135409-5.s: New test case.  Check for relaxation to a 16-bit backward jump instruction.
* ld-mn10300/i135409-5.t: Linker script for the new test.
* ld-mn10300/i135409-5.d: Expected disassembly of new test.
* ld-mn10300/mn10300.exp: Run the new test.
