microblaze: 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-microblaze.c (microblaze_elf_relocate_section): Don't
generate dynamic relocation if UNDEFWEAK_NO_DYNAMIC_RELOC is
true.
(allocate_dynrelocs): Discard dynamic relocations if
UNDEFWEAK_NO_DYNAMIC_RELOC is true.
