kconfig: use $K64BIT to set 64BIT with all*config targets
The variable K64BIT can now be used to select the
value of CONFIG_64BIT.
This is for example useful for powerpc to generate
allmodconfig for both bit sizes - like this:
make ARCH=powerpc K64BIT=y
make ARCH=powerpc K64BIT=n
To use this the Kconfig file must use "64BIT" as the
config value to select between 32 and 64 bit.
