  Put the custom tarball in some other location (which may, BTW, be
an URL or a scp:// location), not in the dl dir.  Buildroot will
download/copy it to the dl dir.

  Select 'using custom config'.  Then specify a location for your
custom config (which doesn't exist yet).  Then, run
'make linux-update-defconfig' (assuming your kernel is 2.6.33 or later,
otherwise you have to use 'make linux-update-config').  The latter command
will copy the linux-custom/.config file to the location you specified
in menuconfig.
