llvm-ld:

It seems that the generated ASM code cannot be assembled with GCC (wrong output format I guess). Maybe this fails because it calls the MingW gcc.exe and not llvm-gcc.exe? However, is the name "a.out.s" a bug? One extension should suffice. 

Is it planed to include binary writers? (So that the step to go through an external assembler wouldn't be necessary.) 

Interpreting the program with "lli" works, by the way.
