Then I would suggest modifying our build system this way:
Select (1) CPU type in menuconfig and depending on this type we set the 2
parameters.
example:
i586: uname/gcc will use i586 and the Kernel also.
VIAC3-2: uname/gcc will use i686 and the Kernel VIAC3-2

I think otherwise it get's to confusing.

Can you do those changes and check it in ?
