cpu_loop_exit*() functions are declared in accel/tcg/cpu-exec-common.c,
and are not available when TCG accelerator is not built. Add stubs so
linking without TCG succeed.
Problematic files:
- hw/semihosting/console.c in qemu_semihosting_console_inc()
- hw/ppc/spapr_hcall.c in h_confer()
- hw/s390x/ipl.c in s390_ipl_reset_request()
- hw/misc/mips_itu.c

I suppose the s390x kvm-only build didn't catch this because
of compiler optimization:
in s390_ipl_reset_request():
640 if (tcg_enabled()) {
641 cpu_loop_exit(cs);
642 }
and "sysemu/tcg.h" is:
13 #ifdef CONFIG_TCG
14 extern bool tcg_allowed;
15 #define tcg_enabled() (tcg_allowed)
16 #else
17 #define tcg_enabled() 0
18 #endif
