Bug 217278: devel/qt5: doesn't respect CXXFLAGS
https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=217278

patch

I'm building qt5 for armv7 with CXXFLAGS+=-mcpu=cortex-a7 and qt5 doesn't
respect it.
The result is that x11-toolkits/qt5-gui fails to build (missing neon feature):

Build type:    /usr/local/lib/qt5/mkspecs/freebsd-clang (arm, CPU features:
none detected)
