At present gdb/config/*/*.mt, for instance:

./src/gdb/config/mips/embed.mt:
> TDEPFILES= mips-tdep.o remote-mips.o
> TM_FILE= tm-mips.h
> SIM_OBS = remote-sim.o
> SIM = ../sim/mips/libsim.a

there are some change-requests suggesting ways to simplify it:

Flattern sim/ makefile structure

sim/null/ as the default simulator

sim/libsim.a
