GCC command invoked in cross-compiling

I’m trying to cross-compile latest webkit with Qt 4.8.1 and Qt5.0 alpha. 
There is a cross-compiling error in "TextureMapperGL.cpp" on building with Qt 4.8.1, not appearing on building with Qt 5.0 alpha.

Here is the details:

GCC command invoked is added in attachment.

Because this error doesn't appear on building with Qt 5.0 alpha, I'm not sure whether the latest WebKit could support Qt 4.8.
Or did TextureMapperGL not support Qt4.8 on OpenGL ES2 platform?
