powerpc: 32BIT vs. 64BIT (PPC32 vs. PPC64)

Hi, Is there a good way (or a shortcut) to do something like: $ make ARCH=powerpc O=PPC32 [other_options] allmodconfig to get a PPC32/32BIT allmodconfig and also be able to do: $make ARCH=powerpc O=PPC64 [other_options] allmodconfig to get a PPC64/64BIT allmodconfig? Note that arch/x86,
