ld: arm32: fix segfault when linking foreign BFDs [PR32870]

PR ld/32870

The linker may occasionally need to process a BFD that is from a
non-Arm architecture.  There will not be any Arm-specific tdata in
that case, so skip such BFDs when looking for iplt information as the
necessary tdata will not be present.
