[PATCH 1/2] UBUNTU: add support for building selected stages of kernel

BugLink: http://bugs.launchpad.net/bugs/603087
To bootstrap in a cross-compile environment we need to be able to build
the compiler and libc, for this we need linux-libc-dev from the kernel.
However we cannot build the kernel without the compiler. Catch 22.
This patch adds "DEB_STAGE=stage1" variable which skips building kernel
requesting only the linux-libc-dev package.
Based on a patch by Marcin Juszkiewicz <marcin.juszkiewicz at linaro.org>
