[bitbake-devel] [PATCH] hob: populate error_msg when hob receives a CommandFailed event

[Cristiana Voicu]

When Hob receives a bb.command.CommandFailed event, it doesn't show any error,
because the error_msg is empty. If so, it is hard to detect the issue, because
Hob continues to run till it blocks because of an information gap.
