	One other thing you might want to try is to put your object tree in a 
directory that is *not* inside of your source tree.  Currently, we don't 
support using separate object trees that are subdirectories of the 
source tree.

	In other words:

Will work:
==========
SRC_ROOT=/home/yue/llvm
OBJ_ROOT=/home/yue/llvm

SRC_ROOT=/home/yue/llvm
OBJ_ROOT=/home/yue/obj

Might/will not work:
====================
SRC_ROOT=/home/hue/llvm
OBJ_ROOT=/home/yue/llvm/obj
