Write the required settings into a file and use KCONFIG_ALLCONFIG.

Our kconfig files are already complicated enough, and needlessly adding 
more complexity only increases the problems (which would in turn result 
in this Hungarian guy spreading his kconfig FUD even more often).

Tomorrow someone might want to boot an allyesconfig kernel on an old
Pentium-MMX, and the CONFIG_M686=y allyesconfig gives might break his 
boot - another special case in kconfig for an even more exotic use case?

Everyone doing randconfig builds knows that CONFIG_STANDALONE=n is not a 
good idea, and similarly someone trying to boot allyesconfig kernels 
might need a list of options he mustn't enable.

After all, we are not talking about stuff for normal users.
