build: don't print directory for GNUMake

Currently when running make targets the directory is printed on some
operating systems (Linux for example):

$ make lint
make[1]: Entering directory '/work/node'
Running JS linter...
./node tools/eslint/bin/eslint.js --cache --rulesdir=tools/eslint-rules
--ext=.js,.md \
  benchmark doc lib test tools
make[1]: Leaving directory '/work/node'
make[1]: Entering directory '/work/node'
Running C++ linter...

On other operating systems the directory is not printed. This commit
suggests adding a flag to make this consistent for GNUMake by not
printing the directory.
