When LLVM looks up target by triple "x86-none-linux-gnueabi", she will find "c" 
target. It seems that the bug is LLVM's duty.

In ${LLVM}/lib/Support/Triple.cpp:36

 18 const char *Triple::getArchTypeName(ArchType Kind) {
 19   switch (Kind) {
 20   case UnknownArch: return "unknown";
    ...
 34   case tce:     return "tce";
 35   case thumb:   return "thumb";
 36   case x86:     return "i386";
 37   case x86_64:  return "x86_64";
 38   case xcore:   return "xcore";

That is, LLVM only accept triple like i386-XXX. x86 is not accepted.
