Stop generating implicit suffix rules in Makefiles

Browse Source 
Suffix rules are the old-fashioned way of defining implicit rules for make.
We don't need them as we generate explicit rules for all sources we build.

[ChangeLog][qmake] Makefile output no longer contains implicit
suffix rules, as all sources are built using explicit rules.
