ok, so I'll add the optional 'cmdline=' to the newly added 
'-semihosting-config'. since this was not used before, it will not break any 
compatibility.

sure, you can do it, but -kernel and -append will continue to work, as before.

as I said, I offer to catalyse and coordinate development for cortex-m related 
ones, to use them as part of the GNU ARM Eclipse project.

in my patch, the -image was implemented as a kind of special alias, the 
definition was finally copied to -kernel, so it should not break any working 
setup.

but no problem, I'll keep it local to my branch.
