[PATCH v4 01/12] accel/tcg: Add stub for cpu_loop_exit() |

Since the support of SYS_READC in commit 8de702cb67 the
semihosting code is strongly depedent of the TCG accelerator
via a call to cpu_loop_exit().
Ideally we would only build semihosting support when TCG
is available, but unfortunately this is not trivial because
semihosting is used by many targets in different configurations.
For now add a simple stub to avoid link failure when building
with --disable-tcg:
hw/semihosting/console.c:160: undefined reference to `cpu_loop_exit'
