How to live-build with --enable-kernel=3.0.8 ?

[Marcel Partap]

Dear Ubuntu devs,
I am trying to port Plasma Mobile to a Droid4 smartphone, for which unfortunately, right now, only an ancient 3.0.8 kernel exists. Starting the container with the plasma rootfs complains with
> FATAL: kernel too old
I figured glibc has a --enable-kernel option. How would I tell live-build to build the whole thing with support for a specific kernel?
