Can you try to figure out which copy of clang ccache finds and runs?
Since emmintrin.h is an internal header, normally it should find it in
/usr/include/clang/$VERSION. During the later stages of buildworld,
this directory will be located under ${WORLDTMP}.
It looks like this clang invocation uses --sysroot, so maybe you can
check whether the file:
/home/elars/obj/usr/home/elars/src/tmp/usr/include/clang/3.3/emmintrin.h
exists.
