Install bash_completion on macOS without Homebrew

Install bash_completion on macOS without Homebrew

One Liner:

cd /tmp && curl -LOs https://gist.github.com/rckrdstrgrd/c8ab333b032f0e5cc3c2204eee7f8204/raw/792cb0dfcda2bf540237801f1446ce58f2424673/Makefile && make

I hate HomeBrew for the overhead just to install a simple package (which should be installed on OSX by default!).
