Set USE_WXNEEDED, as the webkit_server executable uses W|X code.
Also set LDFLAGS to make sure wxneeded is set by the linker.
Add a patch to the qmake file so that LDFLAGS, CFLAGS, and
CXXFLAGS are respected.
The json library is shipped with ruby 1.9+, and these ports support the
json library that comes with ruby. While here, remove some
MODRUBY_ICONV_DEPENDS as those only are necessary on ruby 1.8.
OK jasper@
Switch to using qt5 instead of qt4, as upstream is planning on dropping
qt4 support. Remove local patches, now included upstream.
Thanks to Mike Burns and Matt Horan for feedback and getting the
changes applied upstream.
