No, it isn't. The correct mailing list would be the interest@ mailing list, 
since you're only asking about how to use Qt for a particular scenario, not 
how to change it. When you reply, please drop the development@ mailing list.

If you were asking how to backport the changes from Qt 5 to Qt 4.8, then 
development@ would be correct.

Answering your question: you need to do like in any other package out there, 
in the way that it's been done for 20 years:
	[set environment]
	configure -prefix /usr [other options]
	make install INSTALL_ROOT=/prefix/to/your/sysroot
