Here is the output from my current build process (from the status of the
LibreOffice source from last Friday):
Note you can't assume anything over SSE2 in here.
Actually you can't assume anything MMXish or SSEish.

I confused it with amd64 which up to
SSE2:https://wiki.debian.org/ArchitectureSpecificsMemo#amd64

I've no diea about SIMD instuctions bit this suspicously looks like
instructions not in SSE2?
clang (which per defaults gets used for building skia if installed)
spells out explicitely that it's trying to use SSE2:

I think skia should be patched (at least on i386) to not require SSE or
MMX or whatever. Otherwise the only other alternative would be
--disable-skia....
