[LLVMdev] problem compiling the cfrontend on Linux/PPC

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 \
  mkdir pic; \
  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
--------------------------------
