[Buildroot] Results of an all-package build

[Arnout Vandecappelle <arnout@mind.be>]

  Hi all,

  As part of the test of the disable-doc patch I just sent, I built something
approaching an allyespackageconfig for x86_64 with a Sourcery-2012.09 toolchain.
Interesting to look at the results.

- The following fail to build:

  * classpath
  * diffutils
  * gpsd
  * ipsec-tools
  * linux-pam
  * ltp-testsuite
  * matchbox-desktop
  * metacity
  * webkit
  * neard
  * netatalk
  * network-manager
  * pcmanfm
  * pv
  * sconeserver-http-sconesite-image
  * xdriver_xf86-video-geode
  * xdriver_xf86-input-synaptics
  * valgrind (because glibc 2.16 is not supported, needs valgrind bump)
  * xstroke
  * grub
  * uboot (wrong ARCH parameter)

  midori and jamvm are not built because they depend on the above.

  There are a few more that fail to build in my environment if the
libxml2/mesa3d and linux-fusion patches are not applied. Also xenomai
must be extracted manually before the build, otherwise linux fails to
build.

- About 920 packages (host+target) are built, from 843 source
tarballs.

- legal-info succeeds without problems, except that sylpheed's
license file is not correctly defined.

- I also built a 3.2.28 kernel with Xenomai extension (OCF and RTAI
don't have support for that kernel version) and a x86_64 defconfig.

- cramfs fails to build because it's too large; iso9660 fails to
build because of grub.

- Resulting image sizes:

-rw-r--r-- 1 arnout arnout 516M Dec 13 06:15 rootfs.ubi
-rw-r--r-- 1 arnout arnout 508M Dec 13 06:15 rootfs.ubifs

- The output directory (including all these images) is 31GB: 21GB
for build, 6.5GB for images, 2.9GB for host of which 2GB for staging.
The sources (excluding toolchain) are 1.6GB.

- Time for a clean build (without ccache and JLEVEL=3) on my laptop
is 6 hours. A yocto build takes roughly the same time on my laptop,
but has less than half as many packages.

  Arnout
