Buildworld without ccache works fine. Any ideas?

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.
