What you are asking about is outside the scope of gcc.  You need to
teach your simulator to pass environment variables on, or need to find
another way.

Since command line arguments are (sometimes) passed on, perhaps you
could write a short routine that parses MUDFLAP_OPTIONS from there and
calls __mf_set_options.
