AMD 32-bit CPUs never got SSE2 capabilities.
Apart from Qt Webengine related stuff, see also bug 1183493, most tumbleweed
software is still usable on such hardware.
The question is if this testcase makes sense for the i586 Tumbleweed
architecture/port - as long as it is executed on a CPU which does not support
SSE2 it will always fail (or maybe some day Qt Webengine would be compiled
without generation of SSE2 instructions).

But I think a CPU without SSE2 support, Pentium-III or Athlon-XP, makes sense
for OpenQA tests, because when SSE2 instructions creep in to more essential
parts of the distribution it will make Tumbleweed i586 unusable on most real
x86_32 CPUs (all except Pentium-4) which would probably impact its users
seriously.
