On ARM Linux glibc provides a makecontext() that always fails ENOSYS,
so our configure test thinks there is makecontext support but when we
try to use it for coroutines it will fail and we abort.

I have a workaround in qemu-linaro that just forces the makecontext
test to fail on ARM but I don't like that much. It would be better
to either drop our requirement for makecontext (Paolo had some patches
to try to do this IIRC) or to handle it failing at runtime.
