llvm dev - Apr 2007 - [LLVMdev] building llvm-gcc4 with an installed version of llvm

llvm-gcc4 currently references some files from the build directory of 
llvm, but looking through the make file, I haven't yet come across a 
file that llvm-gcc4 needs that isn't installed with llvm. I checked, and 
all the headers for the src and obj are installed into 
${prefix}/include/llvm and ${prefix}/include/llvm-c. All the main object 
files are the same as well. The only difference with binaries are that 
these aren't installed: fpcmp, llvm-PerfectShuffle, and tblgen.

If this is the case, would it be possible to add something to 
llvm-gcc4's configure and Makefile to support building based solely off 
of a specified llvm-config?
