It's missing some support upstream.  Basically the series is this:

https://patchwork.sourceware.org/project/gcc/list/?series=5387&state=*

where I've committed 1/6 and 2/6, thus adding 
__builtin_dynamic_object_size identification to gcc.  However, the 
actual dynamic expression generation is in patches 3-6, which is why the 
tests are failing.

I may not be able to finish updating and pushing all the patches before 
glibc freeze.
