We do need this.  The panic I posted yesterday happened in the 'make'
stage of the below sequence:

    cd /sys/<arch>/conf
    config FOO
    cd ../compile/FOO
    make clean

Note that the kernel.debug matching the running kernel was blown away at
this point.

I was going to just install kernel.sym instead of a kernel with symbols,
but kgdb's usage doesn't claim to support '-s' as the previous kgdb did.
