The code that sets the stack frame back pointer is incorrect for
the setup_rt_frame() code; qemu will abort (SIGSEGV) in some
environments. The setup_frame code was fixed in commit
beb526b12134a6b6744125deec5a7fe24a8f92e3 but the setup_rt_frame
code was not.
Make the setup_rt_frame code consistent with the setup_frame
code.
