Thanks.

This seems right, and works for installing qt5-webkit-debuginfo when I 
gave it a quick try (seems to work on i686 as well).

(Note that if you have an existing build directory, it's important to 
not be an idiot like me, and do a 'make clean' to rebuild everything 
with the new _FILE_OFFSET_BITS define)

(I faintly recall there are some other issues with the use of 'int' for 
the progress reporting gauges, which also might need some attention to 
work correctly for file sizes >2GB)

Anyhow, I applied it, and I'll try to make a release of setup in the 
next few days...
