What is the benefit of this patch?  I'd prefer to keep libstdc++-boot0
identical across architectures for simplicity, unless there is a good
reason to do otherwise (say, porting to a new architecture).

Now we could end up in a situation where someone patches GCC5 on
'master' and accidentally triggers a full rebuild on AArch64.
