Actually you can't assume anything MMXish or SSEish.

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

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....
