qt tarball changed at nokia

[Mark Davies <mark%ecs.vuw.ac.nz@localhost>]

The qt4 tarball at ftp.qt.nokia.com seems to have changed

-rw-r--r--    1 ftp      ftp      220388303 Sep 12 12:59 
qt-everywhere-opensource-src-4.7.4.tar.gz

so doesn't match distinfo.  Don't know what the differences are.

cheers
