--- Comment #36 from Szabolcs Nagy <nszabolcs at gmail dot com> ---
on arm with -static -pie

extern int foo __attribute ((weak));

int
_start ()
{
  if (&foo)
    return foo;
}

has a R_*_RELATIVE reloc which is wrong in pie for undef weak syms.

i think the ld-elf/pr22269-1.rd test should reject relative relocs too.
