Actually, "not allowed" it not the right expression, "discouraged"
would be correct. If upstream requires sse2 then not enabling it would
mean that all users of i386 would not have access to this software,
even though one can assume that the majority uses hardware that is sse2
capable.
Without looking at "sortmerna", having an unconditional include of
emmintrin.h and no mechanics that enable -msse2 from within the build
system seem to be good indicators that upstream didn't implement any
other code path.
I think this discussion could be helpful (linking to the conclusion of
the maintainer):
