thanks

13-multiarch-newpath.patch doesn’t quite work.  First, GccTriple is the 
empty string, because it’s only set to anything else if the non-multiarch 
path exists.

  std::string GccTriple = "";
  if (Arch == llvm::Triple::arm || Arch == llvm::Triple::thumb) {
    if (!llvm::sys::fs::exists("/usr/lib/gcc/arm-linux-gnueabi", Exists) &&
        Exists)
      GccTriple = "arm-linux-gnueabi";
  } else if (Arch == llvm::Triple::x86_64) {
    if (!llvm::sys::fs::exists("/usr/lib/gcc/x86_64-linux-gnu", Exists) &&
        Exists)
      GccTriple = "x86_64-linux-gnu";
  } …

Second, on i386, the multiarch triple (DEB_HOST_MULTIARCH=i386-linux-gnu) 
is different from the GCC triple (DEB_HOST_GNU_TYPE=i486-linux-gnu), so 
you’ll get the wrong path:

$ dpkg -c gcc-4.6_4.6.0-13_i386.deb | grep crtbegin.o
-rw-r--r-- root/root      1684 2011-06-11 19:29 ./usr/lib/i386-linux-gnu/gcc/i486-linux-gnu/4.6/crtbegin.o
