Run configure with -v option to see the configure log. Anyhow, there's indeed
No compile time check... configure.exe in qt4 just sets it to 'NO'.

Actually the configure option is new in 4.8.4, and a backport from qt 5.0 :

Unfortunately the following fix for the multiple defines issue wasn't backported:

https://codereview.qt-project.org/#change,29140

I uploaded

https://codereview.qt-project.org/53769

to fix it in the next qt 4.8 release.

So ... LFS is enabled with 4.8.4 on MinGW by default, and the configure output is just plain wrong. Just ignore it.
