* sim-options.c (standard_options): Add --endian.
(standard_option_handler): Likewise.
* nrun.c: #include <signal.h>.
(main, cntrl_c): Wrap calls to sim_resume in a SIGINT
handler that calls sim_stop ().

/* ??? One might want to conditionally compile out the entries that
aren't enabled. There's a distinction, however, between options a
simulator can't support and options that haven't been configured in.
Certainly options a simulator can't support shouldn't appear in the
output of --help. Whether the same thing applies to options that haven't
been configured in or not isn't something I can get worked up over.
[Note that conditionally compiling them out might simply involve moving
the option to another table.]
If you decide to conditionally compile them out as well, delete this
comment and add a comment saying that that is the rule. */
