* 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

(elf_cris_adjust_gotplt_to_got): Assert integrity of the gotplt
refcount in relation to the plt refcount.
