[Bug ld/22269] Undefined weak symbols isn't resolved to 0 in static PIE

I agree that undefined weak symbols probably ought to resolve to 0 in a static
PIE.  To do that on ppc it would be reasonable to add the following to elf32.em
after_parse

  if (link_info.dynamic_undefined_weak == -1
      && link_info.nointerp)
    link_info.dynamic_undefined_weak = FALSE;

or perhaps something a little more specific to static PIE..

However, that results in
FAIL: ld-i386/pr19636-1d
FAIL: ld-i386/pr19636-1e
FAIL: ld-i386/pr19636-1f
FAIL: ld-x86-64/pr19636-2d
FAIL: ld-x86-64/pr19636-2e
FAIL: ld-x86-64/pr19636-2f

So, why does x86 make undefined weak symbols dynamic in the -d tests (which are
-pie --no-dynamic-linker)?
