That is very similar to what I use, except I build LLVM for release
(--enable-optimized).

FWIW my script that builds llvm from a cronjob looks like this, and it
works:
rm -rf $DIR/install &&
rm -rf $DIR/llvm-obj &&
rm -rf $DIR/llvm-gcc-obj &&
mkdir $DIR/install &&
mkdir $DIR/llvm-obj &&
mkdir $DIR/llvm-gcc-obj &&
cd $DIR/llvm && svn up &&
cd $DIR/llvm-gcc4.2 && contrib/gcc_update &&
cd $DIR/llvm-obj &&
../llvm/configure --enable-optimized --prefix=$DIR/install &&
make -j4 >/dev/null &&
make install &&
../llvm-gcc4.2/configure --prefix=`pwd`/../install
--program-prefix=llvm- --enable-llvm=$DIR/llvm-obj/ --disable-multilib
--enable-languages=c,c++ &&
make -j4 >/dev/null &&
make install
....
