build: Enable SSSE3 sc12 converters by build switch only
The existence of SSSE3 intrinsic headers is not a sufficient condition that SSSE3 support is available, which may lead to 'illegal instruction' runtime failuire on some platforms. Major OS distributions (Ubuntu, Fedora, etc.) include x86_64 intrinsic headers, though the underlying architecture may or may not support the instruction set. Assuming SSE2 availability is safe as instructions are present on all x86_64 architectures for which instrinsic headers would be present. The same cannot be said for SSSE3. Issue: #1761
