gdbstub: Add a missing case of signal number translation in gdbstub
While using qemu with gdb "target remote" to debug an application that uses fork and exec, the qemu process receives SIGSTOP every time the forked process terminates (sending SIGCHLD). This is caused by a missing call to gdb_signal_to_target in gdbstub.c, which is fixed by this patch: Signed-off-by: Martin Simmons <martin@lispworks.com> Reviewed-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
