This failure is specific to -mno-accumulate-outgoing-args (-Os is just a
shortcut for this looong-worded compile flag). With -mn-a-o-a, compiler tries
to push everything to the stack. Since there is no "push %xmm", compilation
breaks.
I can put "-O2 -mno-accumulate-outgoing-args" into dg-options if this is more
informative, but there is no need for torture to cycle all optimization flags.
