Qt4 shouldn't require X11, even on Unix

[Thiago Macieira]

This section of FindQt4.cmake seems bogus to me:

  IF(UNIX)
    # on OS X X11 may not be required
    IF (Q_WS_X11)
      FIND_PACKAGE(X11 REQUIRED)
    ENDIF (Q_WS_X11)

It's not necessary to have X11 headers in order to compile Qt4 
applications or KDE 4 ones. There are no X11 headers included in any 
public Qt4 application.

I believe the requirement should be only in kdelibs and kdebase (because 
of workspace). Other applications should require X11 on a case-by-case 
basis. It'll also make it easier to tell which applications are not 
portable.

I guess we'll have to wait for the 4.2-unfreeze.
