Hi,

The attached patch is to fix PR target/50068.  sh_output_mi_thunk
calls dbr_schedule which doesn't expect to be called in that
situation.  Although we could set the environment in output_mi_thunk
in such a way to enable dbr_schedule, it looks a bit overkill for
this relatively rare optimization.
The patch simply removes that use of dbr_schedule.  Tested on
sh4-unknown-linux-gnu with no new failures.  Applied on trunk.

Regards,
	kaz
