Provide a detailed description of the proposed feature

Add a flag that adds linuxbrew to the end of path instead of the start.

What is the motivation for the feature?

On my linux system, I prefer using system installed binaries before homebrew install ones.

How will the feature be relevant to at least 90% of Homebrew users?

It let them use system installed binaries instead of all homebrew binaries. This may also affect SUID root binaries like mount.

What alternatives to the feature have been considered?

Using some sort of complicated sed statement.

To what?

/home/linuxbrew/.linuxbrew/bin/brew shellenv. Mabye add --end-of-path

If it's not added to the front of your PATH brew doctor will (intentionally) complain. Sorry, passing on this.
