x86: Keep _GLOBAL_OFFSET_TABLE_ for .eh_frame

Since x86 .eh_frame section may reference _GLOBAL_OFFSET_TABLE_, keep
_GLOBAL_OFFSET_TABLE_ if there is dynamic section and the output
.eh_frame section is non-empty.

	PR ld/33499
	* elfxx-x86.c (_bfd_x86_elf_late_size_sections): Keep
	_GLOBAL_OFFSET_TABLE_ if there is dynamic section and the
	output .eh_frame section is non-empty.
