This seems to work but I would still like to try and find a way to
generate the .config file I want without having to run menuconfig at
all.  I think what I would really like is something like:

  make ARCH=mips CROSS_COMPILE=mips-linux-gnu- ENDIAN=little \
     ISA=mips32 defconfig

Where the ENDIAN value and the ISA value would, somehow, change the
default settings in the generated .config file from big-endian to
little-endian and from mips1 to mips32.  But I am not sure that there
is any way to pass in values like that from the make command into the
values used by defconfig.
