cris: Check UNDEFWEAK_NO_DYNAMIC_RELOC

Don't generate dynamic relocation against weak undefined symbol if it
is resolved to zero.  FIXME: UNDEFWEAK_NO_DYNAMIC_RELOC may need to be
checked in more places.

bfd/

	PR ld/22269
	* elf32-cris.c (cris_elf_relocate_section): Don't generate
	dynamic relocation if UNDEFWEAK_NO_DYNAMIC_RELOC is true.
	(cris_elf_check_relocs): Don't allocate dynamic relocation
	if UNDEFWEAK_NO_DYNAMIC_RELOC is true.

ld/

	PR ld/22269
	* testsuite/ld-cris/weakhiddso.d: Update and remove R_CRIS_NONE.
