This patch-set adds support for building barebox with an auxiliary config.
It can be used to build the barebox x-loader or MLO (also called Secondary
Program Loader) in addition to the standard barebox build (Tertiary Program
Loader). This implements the design proposed in
http://elinux.org/Buildroot#Todo_list, with minor adjustments:
1. Have boot/barebox contain the common stuff.
2. Move the non-shared parts to boot/barebox/barebox and duplicate it in
   boot/barebox/barebox-aux.
3. There is only one version selection, but each package allows to
   define the configuration to be used.
4. Design is a little bit like package/gcc, where we have multiple gcc builds,
   but share a lot of common definitions between the packages.

To demonstrate that it works as advertized, the last patch adds a defconfig for
the beaglebone that makes use of the added functionality.

Revision history:
v6: Review rework based on feedback from Thomas Pettazoni:
    - Second config build renamed to auxiliary build.
    - Primary package build moved to boot/barebox/barebox to keep things symmetric.
    - Dropped already merged parts of series.
v5: Review rework based on feedback from Arnout Vandecappelle, Yegor Yefremov
    and Thomas Petazzoni:
    - Dropped support to rename output/images (same can be achieved with
      genimage)
    - Simplified barebox INSTALL_IMAGE_CMDS
    - Simplified KConfig option naming
    - Appends test defconfig to last commit message
    Improvements to the BBB barebox test config:
    - Latest kernel and headers
    - Tunes barebox.env to boot from eMMC/SD
    - Use genimage to generate a full sdcard.img
v4: Introduces barebox-package function to reduce duplication and maintenance
    Simplifies built image selection
    Ease review with smaller patches
    Review re-work: Special thanks to Arnout Vandecappelle and Yegor Yefremov
v3: Updated for master at 544e2c5871f223facd1ab3c2853cd07ad70dd9d1
v2: Dropped x-loader build specialization in favor of 2 generic barebox builds
v1: Initial posting

No functional changes. In preparation for the auxiliary barebox build,
boot/barebox is split into two parts:
1. boot/barebox:
   - The source and patch specification which are to be shared between the
     barebox and barebox-aux packages.
   - The barebox-package function and build logic.
2. boot/barebox/barebox:
   - The package configuration, fragments, barebox env, etc.
   - The actual barebox package make instantiation.

Adds support to build barebox with an auxiliary config.

This is useful for building an SPL (Secondary Program Loader) in addition to
the traditional TPL (Tertiary Program Loader). The Beaglebone Black for example
has two barebox configurations:
- am335x_defconfig builds the full barebox bootloader with device tree, and
- am335x_mlo_defconfig builds the smaller MLO bootloader that loads the full
  barebox bootloader from the eMMC or SD card.

Tested with the following defconfig:

  # architecture
  BR2_arm=y
  BR2_cortex_a8=y
  BR2_ARM_EABIHF=y

  # system
  BR2_TARGET_GENERIC_HOSTNAME="beaglebone"
  BR2_ROOTFS_DEVICE_CREATION_DYNAMIC_DEVTMPFS=y
  BR2_TARGET_GENERIC_REMOUNT_ROOTFS_RW=y

  # filesystem
  BR2_PACKAGE_AM33X_CM3=y
  BR2_TARGET_ROOTFS_EXT2=y
  BR2_TARGET_ROOTFS_EXT2_4=y

  # bootloader
  BR2_TARGET_BAREBOX=y
  BR2_TARGET_BAREBOX_BOARD_DEFCONFIG="am335x"
  BR2_TARGET_BAREBOX_IMAGE_FILE="images/barebox-am33xx-beaglebone.img"
  BR2_TARGET_BAREBOX_CUSTOM_ENV=y
  BR2_TARGET_BAREBOX_CUSTOM_ENV_PATH="board/beaglebone/barebox/barebox.env"
  BR2_TARGET_BAREBOX_AUX=y
  BR2_TARGET_BAREBOX_AUX_BOARD_DEFCONFIG="am335x_mlo"
  BR2_TARGET_BAREBOX_AUX_IMAGE_FILE="images/barebox-am33xx-beaglebone-mlo.img"

  # kernel
  BR2_LINUX_KERNEL=y
  BR2_LINUX_KERNEL_USE_DEFCONFIG=y
  BR2_LINUX_KERNEL_DEFCONFIG="omap2plus"
  BR2_LINUX_KERNEL_ZIMAGE=y

  # use the barebox built-in dtb
  # BR2_LINUX_KERNEL_DTS_SUPPORT is not set

* Builds the barebox MLO and bootloader.
* Generates a bootable SD card image with boot and rootfs partitions.
* Barebox integrates a perfectly good device-tree for the bbb, so no dtb is
  being generated with the kernel.

Thanks for this new version, looks good to me! I'll wait for Arnout to
comment and see if he has objections to this way of doing things.

only difference is to use Barebox instead of U-Boot.
