Can you share your configure options?

Also, it looks like you are forcing at least -mfdpic when running the
testsuite? 

Why did you put "known to work 9.2", since -mfdpic does not exist in that
version?

Thumb-1 is not supported when using FDPIC.

In arm_option_override, we have:
  if (TARGET_FDPIC)
{
  arm_pic_register = FDPIC_REGNUM;
  if (TARGET_THUMB1)
sorry ("FDPIC mode is not supported in Thumb-1 mode");
}

but using -mflip-thumb overrides this check, and forces thumb-1 mode, hence the
failures.

Yes, the known-to-work is a bit misleading here.
Anyway, the cross compiler is configured like this:
