move emission of final messages to qmake-based configure

now qmake is the last command called by the unix configure script.
as it happens, this was already the case in the windows script, but only
because it didn't print these messages at all, which it implicitly does
now.

another effect of this is that repositories outside qtbase will now also
get the installation note in modular builds, which makes sense.
