I have done something like this to make it work in the past.

+ have a "preinclude.h" (better name possible :) that has something like
  this in it:

#define exit my_exit

  This file should be preincluded using the gcc -include option

+ have my_exit do something like this:

  void exit( int s ) { printf( "Exit Code %d\n", s ); exit(s); }

+ Have a runtest_on_target script that resets the target, runs the code,
  and collects the output.  It can parse the regular output to see the
  Exit Code message and make that number its exit status.

  Some scripting is necessary anyway to automate control of a particular
  target for a download, run, reset sequence.

Probably not ideal but it worked and it could work on any target. :)
