You say you're trying to build Clang with Clang? How come it's using
GCC's SSE headers instead of Clang's headers? Are you sure you installed
Clang properly? (There should be a <prefix>/lib/clang/2.9/include
directory containing the SSE headers.)

And no, Clang can't use GCC's headers. A bunch of GCC built-ins were
purposefully omitted, because Clang doesn't need them (they're all
internal implementation details of GCC's SSE headers).
