Currently there are two problems.
The first is clang generates a preamble (that is always executed) to
stack xmm registers. This causes a ILLOP on the x86_64 softmmu tests
as SSE isn't enabled.
The second is the inline assembler in test-i386.c breaks clangs
compiler and I don't know how to fix it. Even with Theodore's patch
series (d5741445-7efd-4af1-8db2-e4afa93cb...@icloud.com) I still get
compiler failures.
For now lets just skip clang and allow it to fall back to the
containers which we know have compilers which work.
