IIRC, Andras (CCed) has been running FDPIC for a while. Also, I can try to
give it a go on M/R class systems around next week.

I've noticed under Mickael's repo extra patches:

- Add tls support for cortex-m cpu family
- Workaround to fix futex bug on mmu less

It'd be nice if you shed some light on why they are not present in your
series.

Thanks
