For most things you can just copy the source to your application and 
build it there.  The linker will then use your object and skip the 
corresponding one in the rtems library.  Start.o is explicitly linked 
(i.e. not part of a library) so this trick won't work.  I'd suggest 
capturing the linker command that's run as part of your application 
build, copy it to your own shell script and modify this script to link 
your start.o instead of the system start.o.
