Hi,

This is third version of patch series of SystemTap supporting
sysroot and SystemTap script cross compilation, integrated with
OE workflow.

Version 3 Changes:

   * Simplified and cleaned image-combined-dbg class, as per Richard's
     neat suggestion

   * Rebased to latest tree to resolve merge conflict with systemtap
     and gcc-8 recent change

Version 2 Patches, since first, RFC, version [1] the following changes
were done:

   image: add image-combined-dbg helper class

      Needed to create rootfs-dbg that contains both target binaries
      and debug symbols. Instead of IMAGE_GEN_COMBINED_DEBUGFS build
      option as in RFC patches [2], small additional class is
      introduced that allows adding target symbols back into
      rootfs-dbg. The approach was suggested by Khem, as response on
      first RFC patches.

   Revert "systemtap: Cross compilation fix"

      Remove previous OE specific patch. It superseded
      by --sysroot support patch series

   systemtap: support --sysroot option in variety of situations in cross build

      Backport of SystemTap patches required to support --sysroot.
      Since my first post I worked with SystemTap maintainers and
      now all needed fixes for sysroot support got accepted.

   systemtap: create translator packageconfig

      Creates new PACKAGECONFIG, translator, which is on by default,
      but if dropped resulting systemtap package would contain only
      minimal run-time utilities required to activate/run host cross
      compiled SystemTap modules. It is implemented in such way
      instead of separate systemtap-utils recipe based on team's
      feedback.

   crosstap: replace script with new python based implementation

      Full backward compatible replacement of original crosstap
      shell script, written in python with extended functionality
      to support SystemTap scripts for user-land using --sysroot
      option. Compared to RFC version new script invocation wise is
      fully backward compatible with orginal crosstap shell script.

Full setup with patch series and examples that were used for
testing is available at [3].
