Seems impossible. 5.6's mkspecs/macx-clang/qmake.conf contains:

include(../common/clang-mac.conf)

And that file has:
QMAKE_CXXFLAGS += -stdlib=libc++
QMAKE_LFLAGS   += -stdlib=libc++

The hint is in that "-O3 -march=native" in the command-line. The only place 
where "-march=native" shows up in the Qt sources is part of ANGLE [*], which 
is never compiled on OS X.

So I conclude that René has overwritten QMAKE_CXXFLAGS.

[*] that's a bug
