libXext was only needed (as a library) by QT when it was using
XLib/libX11 (as a library), now that we're building QT without
XLib/libX11, we can safely remove libXext.
We're no longer building QT with libX11/XLib, however, libX11/XLib
headers are still required for parts of QT. In this commit we add a
minimal configure.ac for libX11/XLib that is headers-only.
This change allows us to remove all of libX11/XLib's dependencies.

qt5.7 changed the location of some of its symbols, creating a circular
dependency in Qt5Core. Rather than trying to fix that up, build our own zlib
rather than having it built for us.
We're not ready to switch to a static qt5 for Linux yet due to missing plugin
support. This adds a recipe for building a shared qt4 that we build and link
against, but don't distribute.
make USE_LINUX_STATIC_QT5=1 can be used to build static qt5 as before.
