[oe] [meta-qt5][PATCH v5] Upgrade to Qt 5.8

[Johannes Pointner]

I'm building for i.MX6. The problem is that the build is failing
because the egl CFLAGS are not set:

| In file included from
/mnt/raid/yocto_env/poky/morty/ppt50/build/tmp/sysroots/ppt50/usr/include/EGL/eglplatform.h:38:0,

error: #error "Platform not recognized"
|  #error "Platform not recognized"

This flags are used inside the eglvivante.h to get the correct
platform. There is a pkconfig file which defines them: Cflags:
-I${includedir} -DLINUX -DEGL_API_FB -DWL_EGL_PLATFORM

Before the update to Qt5.8 there were a patch for the configure file
to set these variables:

+ if [ -n "$PKG_CONFIG" ] && $PKG_CONFIG --exists egl 2>/dev/null; then
+ QMAKE_INCDIR_EGL=`$PKG_CONFIG --cflags-only-I egl 2>/dev/null | sed
-e 's,^-I,,g' -e 's, -I, ,g'`
+ QMAKE_LIBS_EGL=`$PKG_CONFIG --libs egl 2>/dev/null`
+ QMAKE_CFLAGS_EGL=`$PKG_CONFIG --cflags egl 2>/dev/null`
+ QMakeVar set QMAKE_INCDIR_EGL "$QMAKE_INCDIR_EGL"
+ QMakeVar set QMAKE_LIBS_EGL "$QMAKE_LIBS_EGL"
+ QMakeVar set QMAKE_CFLAGS_EGL "`echo " $QMAKE_CFLAGS_EGL " | sed -e
's, -I[^ ]* , ,g;s,^ ,,;s, $,,'`"
+ fi

This patch was removed, so my question is how should this work now?
A workaround is to set this variables in the linux-oe-g++.
I also tried to use the device option: -device linux-imx6-g++ but this
failed with the following error even if the path was correct.

| Project ERROR: CROSS_COMPILE needs to be set via -device-option
CROSS_COMPILE=<path>
| Could not read qmake configuration file
