Answer 1

After attempting implement the fix described in the question I eventually found the following (clearly this in only a solution to linux's that use the freedesktop concept of .desktop files):

The line in "/usr/local/share/applications/Nokia-QtCreator.desktop" was:

Exec=/opt/qtcreator-2.5.2/bin/qtcreator.sh %F

I changed it to:

Exec=env MAKEFLAGS=-j16 /opt/qtcreator-2.5.2/bin/qtcreator.sh %F

And got the functionality requested in the question.

Ok, I have no idea why following the instructions in the question I didn't get there but I didn't. I hope this explanation will help someone.
