A Makefile to automatically build Xenomai kernel packages for many
Debian/Ubuntu release and architecture combinations

---------------------------
Prerequisites:

The pbuilder and reprepro packages must be installed, in addition to
the usual kernel development environment.

    apt-get install pbuilder reprepro

---------------------------
Targets:

test:  list some variables and their values for debugging

<codename>/<arch>/.stamp-linux:
    Build the kernel packages (automatically builds the xenomai packages)

<codename>/<arch>/.stamp-xenomai:
    Build the xenomai packages (automatically builds the base.tgz chroot)

<codename>/<arch>/.stamp-kmodule:
    Build kernel module packages (automatically builds the kernel packages)
    This builds the r8168 kernel modules

<codename>/<arch>/base.tgz:  e.g. precise/base-i386.tgz
    Build the base chroot tarball with pbuilder --create

Codename is one of wheezy, squeeze, precise, lucid

Arch is one of amd64, i386

Most simply, just run 'make' to build all packages for all
<codename>/<arch> combos.

---------------------------
What it does

For each <codename>/<arch> combo:
- Downloads sources, checks out git repos, builds gpg keyring
- Creates a base pbuilder chroot tarball
- Builds the Xenomai runtime packages
- Builds a local PPA with the Xenomai runtime packages, needed for the
  kernel build
- Updates the pbuilder chroot tarball with the new PPA
- Builds the Xenomai kernel package
- Builds the r8168 kernel module

Package results go into <codename>/<arch>/pkgs.

---------------------------
TODO

- build only binary packages
  - build arch-indep binary packages only once
- timestamps are used in many targets, but these should probably be
  replaced with something more specific
- build smictrl packages
