[RFC][PATCH 2/2] meta-toolchain-arago-minimal: define minimal devkit/sdk

[Jacob Stiffler]

* This minimal sdk can use package management to obtain needed dev
  packages.
* Resulting shar image is ~45 MB
* Usage could be a little more elgant, but if feeds are available,
  the following can be done to install any package availble on a feed:

  $ cat ./sysroots/<target_sysroot>/etc/opkg/* > ./opkg.conf

  $ ./sysroots/<host_sysroot>/usr/bin/opkg --volatile-cache -f ./opkg.conf \
        -t $(mktemp -d) -o ./sysroot/<target_sysroot> update

  $ # To restore current tisdk sysroot (plus unuseable binaries)
  $ ./sysroots/<host_sysroot>/usr/bin/opkg --volatile-cache -f ./opkg.conf \
        -t $(mktemp -d) -o ./sysroot/<target_sysroot> install \
        packagegroup-arago-toolchain-tisdk-target

* This also has the potential to create new rootfs from feeds. Initial
  testing showed problems with setting ownership of files to root. The
  host sysroot does provide pseudo, so it seems possible without using
  root on the host.

meta-toolchain-arago already handles all the above, including feeds and 
package-management. It may not be very minimal, sure, but at least it contains 
the minimal toolchain to be useful. I'd rather look into shrinking existing 
meta-toolchain-arago, especially since there's a larger version called 
meta-toolchain-arago-tisdk...
