You're absolutely right for any target that uses generic_load().  It only
sets the PC.

But targets that use their own loading mechanisms do the weirds't things.
I was recently having to set manually the SP plus a few other things to one
of this beasts.  They have now added it to their startup code, as you say,
and we could use the standard generic_load().
