* elf32-i386.c (elf_i386_check_relocs): Don't cast a unary & 

address operator, as that breaks GCC's strict aliasing rules.
(elf_i386_size_dynamic_sections): Avoid the need for type
punning.
* elf64-x86-64.c (elf_x86_64_check_relocs): Don't cast a unary
& address operator, as that breaks GCC's strict aliasing
rules.
(elf_x86_64_size_dynamic_sections): Avoid the need for type
punning.
