Ok, so to summarize, I think SSE should be enabled in gstreamer only if:
* HAVE_EMMINTRIN_H is defined
* __SSE__ is defined

Or something like that...

i386: HAVE_EMMINTRIN_H is defined, but as we can see SSE is not, so the SSE
code should not be used
$ gcc -E -dM - < /dev/null | grep SSE 
$

amd64: HAVE_EMMINTRIN_H is defined and SEE as well, so all is good, we can
compiled in the SSE parts
$ gcc -E -dM - < /dev/null | grep SSE   
#define __SSE2_MATH__ 1
#define __SSE_MATH__ 1
#define __SSE__ 1
#define __SSE2__ 1
$
