Alex Bennée cf22f936f2 tests/tcg: don't allow clang as a cross compiler
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-E4AFA93CBB1A@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.
