Qt invalid installation

I just installed a Linux V2.6.1 image and environment on my 32 bit OpenSuse Linux 13.1 desktop.
Then I built Qt SDK ($ bitbake - k meta-toolchain-qt5)
and Qt target image ($ bitbake -k angstrom-lxde_image) patched in …/local/local.conf with IMAGE_INSTALL_append = “qtbase qtbase-fonts qtbase-plugins cinematicexperience”.
Then I installed SDK (./deploy/sdk/angstrom-glibc-armv7at2hf-v2015.12-toolchain.sh -S)
When in oe-core directory, after issuing . /usr/local/oe-core-i686/environment-setup-armv72hf-vfp-angstrom-linux-gnueabi, I can run qtcreator , bat Qt installation seems to be spoilt.

Devices: Local PC.

Build & Run - Kit Unnamed-GCC (x86 32 bit in /usr/bin)2

Build & Run - Qt versions
Version name Qt 4.8.5 (System) (marked with !)
qmake location: /usr/local/oecore-i686/sysroots/i686-angstromsdk-linux/usr/bin/qmake2
Qt version is not properly installed, please run make install

Qt version 4.8.5 for Desktop: The Qt version is invalid : Qt version is not properly installed, please run make install.

It is not possible to compile any project even for the PC environment.

Truly I cannot figure out how to solve this situation; please help.
Thank you for your attention.

After sourcing the script, do you get the correct expected output for

$ echo $OE_QMAKE_CXX
arm-angstrom-linux-gnueabi-g++ -march=armv7-a -mthumb -mthumb-interwork -mfloat-abi=hard -mfpu=neon --sysroot=/usr/local/oecore-x86_64/sysroots/armv7at2hf-vfp-neon-angstrom-linux-gnueabi

Did you start qtcreator in the same shell from where you sourced the script?

After sourcing the script in /opt/oe-core:
echo $OE_QMAKE_CXX is different:
arm-angstrom-linux-gnueabi-g++ -mfpu=vpv3-d16 -march=armv7-a -mthumb -mthumb-interwork
-mfloat-abi=hard --sysroot=/usr/local/oe-core-i686/sysroots/armv7at2hf-vfp-angstrom-linux-gnueabi.
Yes, qtcreator is started in /opt/oe-core.

Please note that if in Build&Run-Kit I leave the mouse on (!)Local PC, the following window appears:
