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
