PR31872, Segfault in objdump (elf_slurp_reloc_table_from_section)

Browse Source 
This one was triggered by trying to dump an AMDGPU object.
elf64-amdgcn.c lacks support for objdump relocation handling.

	* elfcode.h (elf_slurp_reloc_table_from_section): Don't segfault
	on NULL elf_info_to_howto_rel.
