But what does "doesn't support SSE" mean?

If it means that the interface to audit functions doesn't provide 
information about SSE register contents, then indeed any parts of the 
tests that rely on the interface providing such information can't be run 
for i386.  But it should still be the case that audit functions for i386 
can be ordinary C functions making use of SSE and AVX, and so clobbering 
any registers that are call-clobbered, without this interfering with 
function arguments or return values that are passed in such registers 
(where the i386 ABI involves use of SSE registers for argument passing or 
return, this should still work when the function being called is in a 
shared library).  And so to the extent that the tests verify that such 
audit functions with incidental use of SSE or AVX work, they should be run 
for i386 - for example, I see nothing in tst-audit3 that should be 
inapplicable to i386.  (If in fact such functions don't work, that's a 
separate bug.)
