Subject: [PATCH] kconfig: don't select 64 bit option on sparc32 all{yes,mod}config

The SPARC architecture provides 64BIT config option to select
build type and it is set to 1 on ARCH=sparc64 as a default value.
But in case of 32-bit, it is also set to 1 by the allyesconfig
logic, end result would be the same as of sparc64. So I think
it would be better if plain ARCH=sparc all{yes,mod}config do not
set it then we can test 32-bit build by default.
