Turn off Link Time Code Generation (/LTCG) by default
Turning on LTCG affected too many projects, where customers applications
would take a long time linking, severly affecting their development time
(even though it was only added for release builds)
We turn it off by default, and add a -ltcg configuration option, and the
possibility to also do CONFIG+=ltcg in projects, should they not want it
for Qt, but in their own projects. (Same, they can build Qt with it, and
do CONFIG-=ltcg for their project)
