The setting of DESTDIR causes it to try to write the install path 
(e.g. /usr/lib) during "make", which fails. This is not so bad. Bad is 
however that there is no install rule created, so the library will not be 
installed at all. In addition the INSTALL_ROOT feature of qmake (needed for 
binary packages) is not available. the patch fixes those isses by building 
the library locally and then adding a install rule that also respects 
$INSTALL_ROOT.

Ah, ok. This diff should do it then:
