In fact, i am using the CFE build procedures. I am on instructions 5.

Okay, I took a closer look at your output.

I was correct in that gccas is attempting to assemble a native PPC 
assembly language file.  However, this appears to be happening because 
the assembly file is generated by the GCC Makefiles for libgcc2 (in 
llvm-gcc/gcc/config/rs6000/t-ppccomm, I think).

The first thing I would try is Marco's suggestion: add 
--disable-multilib to the configure command line and rebuild.  Hopefully 
this will disable the generation of this assembly code.

If that doesn't work, then you will need to comment out stuff in 
llvm-gcc/gcc/config/rs6000/t-ppccomm and try to rebuild (you may need to 
reconfigure and rebuild).  Hopefully, we will not need to create LLVM 
equivalents of this assembly code; I think it's there for ABI 
compatibility and shouldn't be needed by LLVM.

it doesn't work for me

i edit the file llvm-gcc/gcc/config/rs6000/t-ppccomm and remove some
targets from the variable EXTRA_MULTILIB_PARTS (bug stop after bug stop)
:

-------------------------------------------------------------
EXTRA_MULTILIB_PARTS = crtbegin$(objext) crtend$(objext) \
  crtbeginS$(objext) crtendS$(objext) crtbeginT$(objext)
-------------------------------------------------------------

Now, it stoppes there:

gmake[1]: Entering directory
`/usr/local/home/cyrille/project/llvm/cfrontend/build/powerpc-unknown-linux-gnu/libiberty'
if [ x"" != x ] && [ ! -d pic ]; then \

  else true; fi
  touch stamp-picdir
  CONFIG_FILES= CONFIG_HEADERS=config.h:config.in /bin/sh
  ./config.status
  config.status: creating config.h
  config.status: config.h is unchanged
  config.status: executing default commands

--------------------------------
.... (xgcc compilation with no error), then
