When setting up the pointer for the sigreturn stub in the return address register (r14) we currently use the host frame address instead of the guest frame address. Note: This only caused problems if Qemu has been built with --disable-pie (as it is in distros nowadays). Otherwise guest_base defaults to 0 hiding the actual problem.
