compile a few simh simulators

simh_compile.sh

#!/usr/bin/env bash
#
# The nice cmake parallel compile system that simh offers fails 
# on console only linux systems that do not have X11 / SDL / MESA graphical libraries
# as some sims require them.  Perhaps there is some configuration for this.
# For now I am just compiling the couple of sims that I use single threaded.
# If this gets slow and/or annoying then look at cmake again.
