elflink.c: miscellaneous formatting/style fixes

	* elf32-arm.c (elf32_arm_check_relocs): Use dynobj rather than
	reading the same from htab.  Remove unnecessary casts.
	Formatting.
	(elf32_arm_late_size_sections): Remove unnecessary cast.
	* elfnn-aarch64.c (elfNN_aarch64_check_relocs): Likewise.
	(elfNN_aarch64_late_size_sections): Likewise.
	* elf32-metag.c (elf_metag_check_relocs): Likewise.
	* elf64-alpha.c (elf64_alpha_check_relocs): Likewise.
	* elfnn-loongarch.c (loongarch_elf_check_relocs): Likewise.
	* elfxx-tilegx.c (tilegx_elf_check_relocs): Likewise.
