Good guess. I have tried this:

1. Compile everything as is.
2. "make check" -> Illegal Instruction. Good.
3. Delete file "celt/tests/test_unit_mathopsi.o".
4. Edit "Makefile" and delete all "-msse*" directives.
5. "make". It should rebuild file "celt/tests/test_unit_mathops".
6. Error:

I didn't check if the resulting library is working correctly. This is a
production machine :-(.
