This sounds like PR61737 (fixed; use 4.9.2 not released yet),
but of course with the above sentence serving as your complete
bug-report (or did I miss one?) that will only be a guess.

(oops. *blush*)  The TLS stuff is unfortunately not upstreamed
at this time.  Unimportant when building the kernel, but
mentioned for completeness.  (The bad excuse is that I
originally awaited pre-v32 kernels to get the corresponding TLS
support so I wouldn't have to do ugly pre-vs.-v32 conditionals,
then the whole thing lost priority, and now I avoid adding code
I can't/won't test - the glibc end isn't upstreamed either.
Sorry.)
