A way for conditionals in qmake (mostly for packaging), and #ifdef. I 
have no particular emotional attachments of how to call these constants 
(also depends on how Sailfish sees itself in terms of future versioning, 
licensing, subsequent releases, etc), but the mechanism used in 
Harmattan is good enough for me - have a .prf that qmake can pull in 
(it's linux enough that I would refrain from OS-style platform scoping) 
and a qplatformdefs.h for the C++ side.
