Hi Yann, Your proposal looks good: it's cleaner + it covers everything supported by uClibc-ng. I also tested with my configuration and it seems fine.

Required for systems that do not have FUTEX support in kernel. Native POSIX Thread Library (NPTL) relies on futexes, so we need to use LinuxThreads instead on that systems.
