Hi!

Please find attached patch for net-firewall/ebtables/ebtables-2.0.10.4-r2.ebuild
to support running 32-bit ebtables on 64-bit kernel.

When net-firewall/ebtables is built with 32-bit toolchain and deployed onto
64-bit kernel, ebtables command is failing with following reason. Adding
'-DKERNEL_64_USERSPACE_32' option to CFLAGS allows it to run on 64-bit kernel.

Attached patch to enable this when 'kernel64_userspace32' USE flag is set.

Thanks,
Raju Konduru

the tool should handle this dynamically instead of being a build-time constant.  otherwise it breaks and needs recompiling when used across diff kernel builds.
