Marek: I don't know if that is supposed to be a case where Linaro is
supposed to fail, but FWIW, a versatileqemu build performed with the
Linaro ARM gcc version from Ubuntu 12.04 would fail to run whereas built
with the Linaro ARM gcc from Ubuntu 12.10 -- 4.7.2 (Ubuntu/Linaro
4.7.2-1ubuntu1) -- it does work. So maybe Linaro fixed their act.

Gerlando, you may have to revise this definition: I think LLVM does
not necessarily translate through assembly language, at least, not
through the target's assembly language, and LLVM assembly language may
count as 'intermediate representation' rather than true 'assembly
language'.

Amicalement,
