Because apparently QtSoftware changed the default compiler options
between those releases. In particular they enabled a MSVC option which
produces improvements during runtime of the library, but needs lots and
lots of space during compilation for the object files. So if you want to
decrease the disk-usage then just remove all the .obj files from your
buildtree.

This is not something that can be fixed in Qt (except by giving up the
improvements, which apparently isn't worth it for QtSoftware). And IMHO
constraining partitions this way is kind of a weak argument with todays
prices on hdd's.
