Since the Kconfig conversion, some developers have reported that Kbuild sometimes fails completely at random. According to the error reports, it seems to occur for any target board, but only on very fast computers.
The log message for the fail case is like this:
make[1]: *** No rule to make target `../arch//cpu/u-boot.lds', needed by `u-boot.lds'. Stop.
It looks like the top config.mk has not been included for *some* reason, and $(ARCH) has been left blank.
I suspect "autoconf_is_current" is not working in some situation.
This commit moves the definition of ARCH, CPU, SOC, etc. to the top Makefile, so they are surely set.

Sorry for leaving this problem so long.
I have never been able to reproduce this bug on my computer, so I am not sure this patch can fix the problem. I wrote this patch based on my guess. (I just tested this patch has no bad impact.)
Tom, York, Stephen,
Could you test this patch fixes the problem?
Yes I will try. It seems to related to specific OS. I have seen it on old CentOS (fast machine though) when running by script. But I haven't been able to reproduce it reliably.
