Precedence: bulk

Removing the extra 'SUBDIR' line from clean and doc build
output. Because it's annoying.. ;-)

Before:
  $ make clean
  ...
  SUBDIR   Documentation
  CLEAN    Documentation

After:
  $ make clean
  ...
  CLEAN    Documentation

Before:
  $ make doc
  BUILD:   Doing 'make -j8' parallel build
  SUBDIR   Documentation
  ASCIIDOC perf-stat.html
  ...

After:
  $ make doc
  BUILD:   Doing 'make -j8' parallel build
  ASCIIDOC perf-stat.html
  ...
