[PATCH] Fix microblaze sim build error

[Martin Liška]

I see the following error for --target=microblaze-elf:

../../../sim/microblaze/interp.c: In function ‘sim_engine_run’:
../../../sim/microblaze/interp.c:147:39: error: passing argument 2 of ‘get_insn_microblaze’ from incompatible pointer type [-Werror=incompatible-pointer-types]

sim/microblaze/ChangeLog:

	* interp.c (sim_engine_run): Use bool instead of int.
