[bitbake-devel] [PATCH 14/16] build/utils: Drop bb.build.FuncFailed

Its hard to see what this exception adds in the current codebase. The logfile
attribute is effectively ignored, the exception doesn't serve a defined
purpose and mostly seems to be worked around.
Remove it entirely. If this does cause output problems, we'll figure
out better ways to address those.
