You need to add:

python
import sys
sys.path.insert(0, '/path/to/glibc/build/nptl')
end

source /path/to/glibc/nptl/nptl-printers.py
add-auto-load-safe-path /path/to/glibc/build/nptl_db

to your gdbinit for it to work.  Martin, I think you need to fix this
up using Pedro's suggestion sooner.  If you're not going to be able to
do it in time then I'll revert the patch until the next release.

This also needs to be fixed.
