Porting Boost.Context to s390x probably can be based on the Glibc
setcontext/getcontext .... stuff. From a first glance this should not be
toooo much effort. We will try to cover this in the toolchain team. As I
understand it it does not appear to be super-urgent since the default
implementation keeps working for S/390?!
