Maybe it's late for a reply but I have a detailed solution to the problem.
Like what people have mentioned in the replies,
you have to specify the target architecture.

Check /3rdparty/javascriptcore/JavaScriptCore/wtf/Platform.h
You will find the defintions for the architectures there.

such as , "__ARM_ARCH_5TEJ__" (this is for ARMv5)

add a line in your ./configure parameters, such as "-D__ARM_ARCH_5TEJ__" , or whichever architecture definition that suits the platform.

The compile problems to do with javascriptcore should go away.
It happened to work for me, at least for qt 4.5.1 and 4.6.2, for ARMv5 architecture.

Hope this helps.
