It appears the v850 targets duplicate a lot of standard settings
tm_p_file=v850/v850-protos.h
tmake_file=v850/t-v850
md_file=v850/v850.md
extra_modes=v850/v850-modes.def
out_file=v850/v850.c
extra_options="v850/v850.opt"
all of which could be avoided by setting cpu_type (which would also fix
this issue). In general targets setting out_file directly like that are
suspect and indicate a missing case in the code setting cpu_type.
