brew doctor warns about chefdk's *-config files

[miketheman]

$ brew doctor
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!

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:
    /opt/chefdk/embedded/bin/finstyle-config
    /opt/chefdk/embedded/bin/ncurses5-config
    /opt/chefdk/embedded/bin/ncursesw5-config
    /opt/chefdk/embedded/bin/pkg-config
    /opt/chefdk/embedded/bin/xml2-config
    /opt/chefdk/embedded/bin/xslt-config

Warning: You have a non-Homebrew 'pkg-config' in your PATH:
  /opt/chefdk/embedded/bin/pkg-config

`./configure` may have problems finding brew-installed packages using
this other pkg-config.

$ chef --version
Chef Development Kit Version: 0.11.2
chef-client version: 12.7.2
berks version: 4.2.0
kitchen version: 1.5.0

I'm not yet certain of the impact, but thought I'd start the discussion here if anyone else has seen this.

Known-issue indeed e.g. #358 (see also https://github.com/Homebrew/homebrew/pull/33687/files)

Update: Less 'violations', but still appearing.

$ eval "$(chef shell-init bash)"

closing this one as a dup of #313 which has a more proactive title.
