Subject: [PATCH] x86: use defconfig as last resort

When using "make oldconfig" with no .config
present try the list from init/Kconfig DEFCONFIG_LIST
before resorting to use one of the defconfigs.

I had the patch in my local tree but never got it posted.
And then I forgot.

I plan to redo this stuff soonish so we have a more
clean and predictive approach.
But the KCONFIG_ stuff was just more fun ;^)
