QOpenGLShader wrap modify shader base on macro GL_FRAGMENT_PRECISION_HIGH

Some gfx drivers simple don't understand ifdef or don't like redefinition

For example android x86 emulator on intel HD (andorid x86 is compiled with GL_FRAGMENT_PRECISION_HIGH)

crash with simply compilation of any quick 2.0 example:

QOpenGLShader::compile(Fragment): ERROR: 0:3: '' : Macro Redefined highp
W/Qt ( 3512):
W/Qt ( 3512):
W/Qt ( 3512): opengl\qopenglshaderprogram.cpp:325 (bool QOpenGLShaderPrivate::compile(QOpenGLShader*)): *** Problematic Fragment shader source code ***
W/Qt ( 3512): opengl\qopenglshaderprogram.cpp:326 (bool QOpenGLShaderPrivate::compile(QOpenGLShader*)): #ifndef GL_FRAGMENT_PRECISION_HIGH
W/Qt ( 3512): #define highp mediump
W/Qt ( 3512): #endif
W/Qt ( 3512): varying lowp vec4 color;
W/Qt ( 3512): void main()

{ W/Qt ( 3512): gl_FragColor = color; W/Qt ( 3512): }

next case:
some mali400 drivers on linux don't compile shaders with this modification (don't understand #ifdef or #define)

How to reproduce
create quick 2.0 app from wizzard and run it on x86 android emulator

Can we simple add some enviroment define that modify hgader compilation like GL_FRAGMENT_PRECISION_HIGH ??
