R_CRIS_16_DTPREL, R_CRIS_32_DTPREL>: Allow use of non-local
	symbols for non-allocated sections.  Don't check whether to
	generate R_CRIS_DTPMOD for non-allocated sections.
	(cris_elf_gc_sweep_hook) <case R_CRIS_32_DTPREL>: Don't
	handle relocation GC:ing if applied to non-allocated section.
	(cris_elf_check_relocs): Similar.
