If the test program in question fails withs SIGILL, Illegal Instruction exception, then you more than likely to run SSE2-capable CPU, such as Intel P4, under control of kernel which does not support SSE2 instruction extentions. See accompanying INSTALL file and OPENSSL_ia32cap(3) documentation page for further information.
