 Oops -- I've meant CONFIG_CPU_MIPS32, of course, which selects a MIPS32
ISA compliant CPU.  CONFIG_MIPS32 (together with CONFIG_MIPS64) selects
between a 32-bit and a 64-bit kernel, and for 2.4 it's not directly
settable -- it's implied by the architecture selected with the ARCH
Makefile variable.

 Sorry for the confusion.
