[PR ld/22269] arm: Avoid dynamic relocs for undefweak symbols in static PIE
With static PIE linking undefined weak symbols are resolved to 0, so no
dynamic relocation is needed for them. The UNDEFWEAK_NO_DYNAMIC_RELOC
macro was introduced so this case can be handled easily, but it was not
applied consistently in the first attempt to fix ld/22269 for arm:
commit 95b03e4ad68e7a90f5096b47df595636344b783a
arm: Check UNDEFWEAK_NO_DYNAMIC_RELOC
This patch fixes spurious relative relocs in static PIE binaries against
GOT entries created for undefined weak symbols on arm*-*, this fixes
FAIL: pr22269-1 (static pie undefined weak)
bfd/ChangeLog:
PR ld/22269
* elf32-arm.c (elf32_arm_final_link_relocate): Use
UNDEFWEAK_NO_DYNAMIC_RELOC.
(allocate_dynrelocs_for_symbol): Likewise.
