Title:
  Failed to build upstream bpf test on Artful/Bionic ppc64le

Status in linux package in Ubuntu:
  Triaged

Bug description:
  Similar to bug 1738962

  Steps:
   1. git clone --depth=1 https://github.com/torvalds/linux.git
   2. sudo apt-get install clang llvm libcap-dev libelf-dev build-essential
   3. Change the Makefile in linux/tools/testing/selftests/ to build bpf 
   4. make

  Result:
   * It complains about missing headers, this issue applies to the Ubuntu 
Artful source tree as well.

  With Artful source tree:
  $ make
  for TARGET in bpf; do         \
        BUILD_TARGET=$BUILD/$TARGET;    \
        mkdir $BUILD_TARGET  -p;        \
        make OUTPUT=$BUILD_TARGET -C $TARGET;\
  done;
