Revisiting this...

Turns out that 'make all' doesn't build the uImage.gz target, which is
what's used on the pistachio_marduk (with pistachio_defconfig) so we
switched the builds back to 'make uImage.gz'.

However, that fails for a few other defconfigs where that target doesn't
work.

What's your recommendation to have this working for all defconfigs?

I'm guessing we should keep 'make all' but fix any defconfigs that are
not building the uImage.gz target?
