bfd, binutils, gas: Remove/mark unused variables
Clang generates a warning on unused (technically, written but not read
thereafter) variables. By the default configuration (with "-Werror"), it
causes a build failure (unless "--disable-werror" is specified).
This commit adds ATTRIBUTE_UNUSED attribute to some of them, which means
they are *possibly* unused (can be used but no warnings occur when
unused) and removes others.
bfd/ChangeLog:
* elf32-lm32.c (lm32_elf_size_dynamic_sections): Mark unused
rgot_count variable.
* elf32-nds32.c (elf32_nds32_unify_relax_group): Remove unused
count variable.
* mmo.c (mmo_scan): Mark unused lineno variable.
binutils/ChangeLog:
* windmc.c (write_rc): Remove unused i variable.
gas/ChangeLog:
* config/tc-riscv.c (riscv_ip): Remove unused argnum variable.
ld/ChangeLog:
* pe-dll.c (generate_reloc): Remove unused bi and page_count
variables.
