This problem is noticed for an embedded system. It has up-to-date
applications and libraries (built via Buildroot) but the toolchain and
kernel are supplied by the SoC vendor (in this case Marvell, formerly
Cavium Networks). Unfortunately their toolchain is lagging behind and
is still using glibc 2.16.

I could handle this patch locally, but I think there may be other
people in a similar situation which would benefit from an upstream
fix.
