Hmm... those are "bootstrapped" tools. But I can't find anything that overrides 
QMAKE_CXXFLAGS.

But you've got things that you shouldn't have. Most likely, whatever added 
-march=native did so by overriding QMAKE_CXXFLAGS.

The proper way of adding options is to modify the mkspec's qmake.conf file or 
to create a new one that include()s the standard one. Anything else is not 
tested.

Yeah, not tested. This is the cause of your problem.
