Patch attached.

This patch with header installation patch ( 
http://mail.cs.uiuc.edu/pipermail/llvmdev/2005-February/003300.html )
let external project (I am test it at my YAFL frontend for LLVM) build using 
installed LLVM version instead using LLVM obj/src dirs.

After patch applying:

If LLVM_SRC_ROOT/LLVM_OBJ_ROOT variables set
project use for build LLVM object/source dir (current behavior)
or else if LLVM_ROOT set
project use for build installed LLVM dir
or else
project can use only LLVM tools in PATHs if installed LLVM dir added to PATH

Also i remove LLVMExmplDir (i not found any it uses in llvm, llvm-java, 
llvm-test CVS modules)
And remove redundent line (as i think):
.PRECIOUS: $(LLVMLibDir)/.dir $(LLVMToolDir)/.dir $(LLVMExmplDir)/.dir

Any comments?
