bfd: fix -Wunused errors with clang 13+
Clang 13 and 14 produce some -Wunused-but-set-{variable,parameter} for situations where gcc doesn't. In particular, when a variable is set and then used in a way to update its own value. For example, if `i` is only used in this way: int i = 2; i++; i = i + 1; gcc won't warn, but clang will. Fix all such errors found in an --enable-targets=all build. It would be important for somebody who knows what they're doing to just make sure that these variables can indeed be deleted, and that there a no cases where it's a bug, and the variable should actually be used. The first instance of this error fix by this patch is: CC elf32-score.lo /home/simark/src/binutils-gdb/bfd/elf32-score.c:450:11: error: variable 'relocation' set but not used [-Werror,-Wunused-but-set-variable] bfd_vma relocation; ^ Change-Id: I2f233ce20352645cf388aff3dfa08a651d21a6b6
