x86: Add GENERATE_DYNAMIC_RELOCATION_P
Add GENERATE_DYNAMIC_RELOCATION_P which returns TRUE if dynamic
relocation should be generated.
* elf32-i386.c (X86_SIZE_TYPE_P): New.
(elf_i386_relocate_section): Use GENERATE_DYNAMIC_RELOCATION_P.
* elf64-x86-64.c (X86_SIZE_TYPE_P): New.
(elf_x86_64_relocate_section): Use GENERATE_DYNAMIC_RELOCATION_P.
* elfxx-x86.h (GENERATE_DYNAMIC_RELOCATION_P): New.
