arm: 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-arm.c (elf32_arm_final_link_relocate): Don't generate
dynamic relocation if UNDEFWEAK_NO_DYNAMIC_RELOC is true.
(allocate_dynrelocs_for_symbol): Discard dynamic relocations
if UNDEFWEAK_NO_DYNAMIC_RELOC is true.
