[pango/matthiasc/for-main: 1/2] tracing: Fix the defines

[Matthias Clasen <matthiasc src gnome org>]

commit 7385ec67122fdd3a181d5df12a63aae18bd8165f

    tracing: Fix the defines
    
    We want to define pango_trace_mark to nothing.
    
    This reveals that we've never compiled these
    calls out before, and there are some warnings
    to be fixed in that case.
