Qbs building want depricated script module

I try make Qbs package for the buildroot. 

I game with Raspberry Pi 3. 

My Buildroot version is 2018.02.

Used Qt 5.9.3

Build src/lib/corelib/corelib.pro wont script module but Qt5Script floppy as deprecated.

QT += core-private network script

and if I try build Qt5Script I have no successt for Raspberry PI 3 becose ARCH not supported in Qt5Script for this board (I set for qmake define QT5SCRIPT_QMAKEFLAGS = DEFINES="_ARM_ARCH_7M_" but WTF_ARM_ARCH_VERSION not supported in Platform.h and not compile)

../3rdparty/javascriptcore/JavaScriptCore/wtf/Platform.h:386:6: error: #error "Not supported ARM architecture"

So! May be I run wrong way and no need build QtScript for Qbs? If Qt5Script is need for Qbs - it is really shit thing  and I have deep cognitive dissonance!

Please help
