Allow XCode without the Command Line Tools to work with homebrew, so it's not necessary to register an Apple Dev ID and/or go to the XCode prefs and download the CLT. Yay! Further, this commit allows to use the CLT solely (without the need for XCode). Saves quite some megs. (Some furmulae require xcodebuild) Of course XCode together with the CLT is still fine and has been tested on 10.7 and 10.6 with Xcode 4 and Xcode 3. Only on Lion or above, tell the user about the options, which are - Xcode without CLT - CLT without Xcode - both (ok, it's not directly stated, but implicit) So if no Xcode is found and we are on Lion or above, we don't fail but check for the CLTs now. For older Macs, the old message that Xcode is needed and the installer should be run is still displayed. If the CLT are not found but Xcode is, then we print out about the experimental status of this setup. Closes Homebrew/homebrew#10510. Signed-off-by: Adam Vandenberg <flangy@gmail.com>
