linuxbrew: Warning: "config" scripts exist outside your system or Homebrew directories

Warning: "config" scripts exist outside your system or Homebrew directories.
`./configure` scripts often look for *-config scripts to determine if
software packages are installed, and what additional flags to use when
compiling and linking.

Having additional scripts in your path can confuse software installed via
Homebrew if the config script overrides a system or Homebrew provided
script of the same name. We found the following "config" scripts:
    /bin/pkg-config

FIX:

PATH=$(getconf PATH)

and re-sourcing .bash_profile
and then, remove PATH=$(getconf PATH)and re-sourcing .bash_profile

Copy from the above link:
Go to the "Syncronize" view (if you don't have it opened, it's in "Window" / "Show View"), populate the list in case it's not loaded, right click the file you want to revert and in the context menu select "Overwrite" to revert to the latest file in the Git server.

You can also check the changes you're going to discard before reverting by selecting "Open In Compare Editor" in the context menu.
