I did build this on arm-linux-gnueabihf with build-many-glibcs.py, so
this is very surprising.  Looking at
sysdeps/unix/sysv/linux/arm/sysdep.h, I wonder if you are building in
thumb mode, and if so, why this isn't covered by build-many-glibcs.py.

Is the comment about the r7 register still accurate?

Thanks,
Florian
