	PR ld/11458
	* elf32-cris.c (elf_cris_copy_indirect_symbol): Remove invalid
	assert of empty pcrel_relocs_copied on the direct symbol.  Instead
	of moving the list from the indirect symbol to the direct symbol,
	merge into any existing list.
	(cris_elf_check_relocs): Store the original section in the
	pcrel_relocs_copied list, not the relocation section.
	(elf_cris_discard_excess_dso_dynamics): Adjust accordingly to find
	the relocation section, for reducing its size.  Change the
	BFD_ASSERT into a check for the section being read-only, and only
	emit warnings and TEXTREL marker when there's an entry for a
	read-only section.
