On Unix, the path separator is ':', whereas on Windows,
it is ';'. This is the first of a series of patch to bring
macbrew's and winbrew's codebases closer together.
The main places the magic constant ':' was being used were:
- the $PATH environment variable
- CMAKE-related environment variables
- pkg-config related environment variables
ClosesHomebrew/homebrew#21921.

We add the bins from all deps instead. Rationale: formula find and use eg. GNU-coreutils versions of things and then break. Only allow formula to use tools that they depend on and expect.
I want to go further and only add include paths etc. for dependencies, I have done some work on this, but I fear it may be impossible. If an include path is eg. /usr/local/lib/foo/include, is it possible to know if this path is bad? Not always AFAICT.
