target_is_non_stop_p and sync targets
gdb.base/maint-target-async-off.exp fails if you test against
gdbserver with "maint set target-non-stop on" forced.
(gdb) run
Starting program: build/gdb/testsuite/outputs/gdb.base/maint-target-async-off/maint-target-async-off
Breakpoint 1, main () at src/gdb/testsuite/gdb.base/maint-target-async-off.c:21
21 return 0;
(gdb) FAIL: gdb.base/maint-target-async-off.exp: continue until exit (timeout)
Above, GDB just stopped listening to stdin.
Basically, GDB assumes that a target working in non-stop mode
operation also supports async mode; it's a requirement. GDB
misbehaves badly otherwise, and even hits failed assertions.
Fix this by making target_is_non_stop_p return false if async is off.
gdb/ChangeLog:
* target.c (target_always_non_stop_p): Also check whether the
target can async.
