This is probably because modprobe is part of your initrd, and it's
compiled with static libraries which didn't have TLS disabled. It makes
sense to compile modprobe static, since it's kind of pointless to rely
on shared libraries that reside on a disk that you can't get to until
you've loaded the driver with modprobe!

I'd ignore this, as modprobe is neither frequently run, nor is it a
"high performance" task.
