AFAIK Debian's i386 architecture does not (yet) require SSE2 (as
witnessed by the existence of the package `sse2-support`).

Where does this instruction come from?
Is it generated by GCC (and if so, why does GCC generate it)?

PS: I hope the i386 port never will require SSE2, since all the
processors I have which support SSE2 also support AMD64.
