gpac: make X11 support optional.
Revert "qt: Default to build in-place and preserve the src"

This reverts commit 9b5f26f358d0f21323ca2eeb5399b73651c347aa.
gpac: fix X11 typo.
Move MacOS.xcode43_without_clt? into Xcode module
Extend Superenv onto ENV instead of defining it on the singleton class
Move setup into an extended callback
Move superbin into Superenv module
Make Superenv activation explicit
Move common stuff to extend/ENV.rb
Move extra stdenv setup to extended callback
Reference self rather than ENV in Superenv module

We want to be able to extend this module onto an arbitrary hash and use
it without mutating ENV, for testing purposes.
