* elf32-cris.c (cris_elf_gc_sweep_hook) <R_CRIS_16_GOTPLT>

	<R_CRIS_32_GOTPLT>: Fix missing update of gotplt refcount for
	global symbols.
	<R_CRIS_8, R_CRIS_16, R_CRIS_32>: New cases for similar missing
	updates of the plt refcount.
	(elf_cris_adjust_gotplt_to_got): Assert integrity of the gotplt
	refcount in relation to the plt refcount.
