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.

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.

* testsuite/ld-cris/weakhiddso.d: Update and remove R_CRIS_NONE.
I couldn't find a simple test case, it happens when ld.so is linked together.
