  What the problem you have? Have you tried svn instead? I think
it's better to use svn head and report any problem you have, since
people *only* care about the latest version. Anyway, try commands
below:

$ clang -ccc-host-triple armv4-none-linux-gnueabi -c hello.c -emit-llvm -o hello.bc
$ llc -O3 -o hello.s -march=arm -mcpu=strongarm1100 hello.bc
$ arm-unknown-linux-gnueabi-gcc -mcpu=strongarm1100 hello.s -static -O3 -o hello

Do you use the same C libraray for Clang and GCC?
