sim: call SIM_AC_OPTION_WARNINGS(no) in remaining ports

We want all ports to opt into extra warnings as the default compiler
settings lets a lot slide.  Opt all the ports that haven't already in
to the warning system.  None of them build with -Werror, so disable
that by default.  Hopefully someone finds these important enough to
start fixing at some point.
