I think the point is that, for one architecture, only the binaries
contain the COMMON instruction set should be shipped in debian,
otherwise the binary will be broken on some users' platforms, so this
patch could be accepted by the upstream but not debian (and other
binary-based distributions). In debian, simply remove the -msse2 flags
should be okay.
