Hi Will,

Thanks for fixing it.  I can confirm that the patch fixes the failures I 
saw on aarch64*-*-elf.

I have to say that it is not ideal to just match one of two cases, as it 
is sensitive to future changes and less accurate.  However I don't have 
a better solution.

I think the patch is also needed for 2.24 branch.

Thanks,
Yufeng
