[Buildroot] qt4 and qt5 side-by-side

[Buildroot] qt4 and qt5 side-by-side

[Arnout Vandecappelle]

  Qt4 and Qt5 are currently not mutually exclusive. As I just found out, 
they really are...

  Qt4 installs qt.conf in $(HOST_DIR)/usr/bin; if you use this with qt5's 
qmake, qmake will spit out bogus configuration options. As soon as you 
commit one of the other qt5 packages, you'll start to get autobuilder 
failures (which are pretty hard to debug as I can testify :-).

  For the time being, I propose to add a 'depends on !BR2_PACKAGE_QT' to
BR2_PACKAGE_QT5. Ideally, QT should become a virtual package with choices 
between qt4 and qt5.

  Regards,
  Arnout

Fine with me. I don't think it's a reasonable use case to support both
qt4 and qt5 in the same system in Buildroot, so I fully support the
idea of adding the depends on !BR2_PACKAGE_QT.

Best regards,

Thomas
