This patch does the same to remote-sim.

(applies on top of the monitor patch)

Managed to get myself an arm-elf toolchain and tested with a
x86_64-unknow-linux-gnu x arm-elf, --target_board=arm-sim,
without regressions.  Does it look OK?

Default results look much better than I was expecting without
tweaking the boardfile.
