On Intel and compatibles, SwissTable can benefit from SSE2 and SSSE3 if
available. Currently, though, it determines availability through a
compile-time check, which pins binary packages to the CPU of the
builder. Correct this:
- Disable SSE2 and SSSE3 on i386. SSSE3 has never been available on
i386 CPUs, and Debian supports some i386 CPUs that lack the
extension (e.g., the Athlon XP).
- Disable SSSE3 on amd64. SSSE3 did not appear until the mid-'00s,
and Debian supports all amd64 CPUs, even going back to the original
Opteron. Keep SSE2 enabled, since all amd64 CPUs support SSE2.
