Help building compat-wireless

[Gary Thomas <gary@mlbassoc.com>]

I'm struggling a bit to build compat-wireless in a cross-build environment.
I normally don't build kernels in-tree, rather I use a build tree, e.g.
   % cd <linux-source>
   % mkdir /tmp/kernel_build
   % make O=/tmp/kernel_build <some_config>
   % make O=/tmp/kernel_build uImage

I can't see how to use this setup with the compat-wireless package.
I tried [all the combinations I could think of] something like this:
   % cd <compat-wireless>
   % make KLIB=<linux-source> KLIB_BUILD=/tmp/kernel_build
However, this seems to not work as all I get are errors like this:
   /local/compat-wireless-2012-02-28/config.mk:242: "WARNING: CONFIG_CFG80211_WEXT will be deactivated or not working because kernel was compiled with CONFIG_WIRELESS_EXT=n. Tools 
using wext interface like iwconfig will not work. To activate it build your kernel e.g. with CONFIG_LIBIPW=m."

Does this process work in my workflow?  What do I need to do to
get it going?

Thanks
