[LLVMdev] Build(s) broken? (was: Re: Buildbots: Apology and Explanation)

I see the buildbots are currently showing no problem on 32-bit linux but
I get the following build error with TOT (out-of-source autoconf build):

[...]

It seems BasicBlockTracing.ll contains assembly instead of LLVM IR.


Also, llvm-gcc also doesn't build for me. Here the error is related to
exception handling:

Is there something suddenly wrong with my system (which hasn't changed
in any way)? I used to be able to build LLVM(GCC) without problems a few
weeks ago...
