bfd:
* elf32-arm.c (elf32_arm_final_link_relocate): Do not turn
branches to undefine weak symbols into branches to the next
instruction if creating PLT entries for those symbols.
ld/testsuite:
* ld-arm/thumb2-bl-undefweak.d, ld-arm/thumb2-bl-undefweak.s: New.
* ld-arm/arm-elf.exp: Run thumb2-bl-undefweak test.
