Because ".config" isn't valid, you need to have $(objdir)/.config be
checked, and in turn that has to depend on the appropriate target (we
have some stage that says that we are configured, I forget which).

I do forget off-hand which methods of doing "something" in a Makefile
are cheap and which result in firing off a subshell. But for a handy
feature for one SoC I want to make sure we don't slow down say the world
build of all 1400 configurations. For a maybe useful example, see how
the "checkgcc6" target is handled, and maybe we can move all of this to
live under arch/arm/mach-socfpga/config.mk and so only get invoked at
all there.
