[OE-core] qt4-x11-free dependence on gtk+

[Peter A. Bigot]

Since "bitbake qt4-x11-free" failed for me until I did "bitbake gtk+", 
qt4-x11-free needs some sort of dependency on gtk+ to avoid the failure 
below.  I'm guessing it's something like the following added to 
qt4-x11-free.inc:

PACKAGECONFIG ??= "${@base_contains('DISTRO_FEATURES', 'x11', 'gtk', '', 
d)}"
PACKAGECONFIG[gtk] = "-gtkstyle,-no-gtkstyle,gtk+"

but since it takes about an hour to build qt4-x11-free on my system I'm 
hoping somebody can tell me whether that's the right approach.
