[Buildroot] Package definition for gst-shark

[Wolfgang Grandegger]

Hello,

I'm trying to implement a Buildroot package for gst-shark [1]. For
"autogen.sh", it clones

  git://anongit.freedesktop.org/gstreamer/common

into it's source tree using "git submodule init/update". I think copying
that directory from the build directory of BR2_PACKAGE_GSTREAMER1 would
do the job. Is there an environment variable pointing to that build
directory? Or how can I construct the path?

Any other ideas?
