dart-sdk/build/gn_run_binary.py
Tess Strickland 14bcf0f3d4 [build] Make app snapshot build failures copy/pastable.
* Use a filename without spaces for the non-existent DFE path.

* Convert a relative path to the executable to an absolute one in
  gn_run_binary so the command can be run outside the build directory
  without editing.

"""Helper script for GN to run an arbitrary binary. See compiled_action.gni.
Run with:
