[PATCH] give nice output when generating barebox.bin and barebox.S

[Uwe Kleine-König]

As a side effect don't build barebox.S when barebox.bin is updated.  I
didn't manage to keep the old behaviour and I consider it cleaner this
way.

Hello,

I rebased this to current master.  The X86 stuff is untouched, probably
it could be integrated, too, but I didn't want to spend the time trying,
if the patch isn't welcome in principle.  Sascha?
