None of these is allowed on i386.

The baseline for i386 in stretch is the Pentium Pro,
that has neither MMX nor SSE.

Please also double-check the compiler flags used on amd64:
MMX and SSE/SSE2 are allowed (and enabled by default) there,
but no more recent SSE versions.

Except when the software uses autodetection for features at runtime,
it is usually a bad idea if there is any kind of hw feature compiler
flag setting when building a Debian package.
