Thanks for the notice. I didn't get the error when I was initially
testing the change, but then noticed that I was working against an
outdated oe-core version. When building with an up-to-date oe-core I see
the errors as well, but regardless of value the PARALLEL_MAKE - even for
non-parallel builds.

I've been spending a considerable amount of time investigating this and
unfortunately didn't find a solution yet. Strange enough it doesn't
happen at all when building with the vanilla upstream source (parallel
and non-parallel build, build directory outside of source directory).

The cause for the errors seems to be the fact that build/src/tuning/
is not created but all other src/ subdirectories are. There was a patch
applied to upstream [1] removing the src/tuning directory from
powertop_SOURCES in Makefile.am, but it doesn't seem to make any
difference whether it is applied or not.

Any help on further investigating this issue would be appreciated...

Thanks
