Can't cross compile using clang

I'm trying to compile gnu which for ARM using clang from x86_64, but I can't seem to get the correct output. After compiling and running 'make' I get resulting ELF file, but when I run 'file which' I get the following:

which: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked, interpreter 
/lib64/ld-linux-x86-64.so.2, for GNU/Linux 3.2.0, with debug_info, not stripped

which would indicate that it wasn't compiled for the correct target, because when I cross compile using gcc, I get the following:

ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), dynamically linked, interpreter 
/lib/ld-linux.so.3, BuildID[sha1]=077463715830376120e14ecd3b8ff9b80ba765cd, for GNU/Linux 3.2.0, with debug_info, not stripped

This is the command I'm using at the moment:

./configure CC=/home/anon/Documents/llvm/llvm-project/build/bin/clang 
-target arm-linux-gnueabi LD=/home/anon/Documents/llvm/llvm-project/build/lib/LLVMgold.so 
LDFLAGS='-fuse-ld=gold' RANLIB=/home/anon/Documents/llvm/llvm-project/build/bin/llvm-ranlib

I've also tried using -host which is what I used when cross compiling with gcc, but that doesn't work either. What am I doing wrong? Please help!

You likely need to pass -target arm-linux-gnueabi as CFLAGS / CXXFLAGS variable. Or, alternatively, you can just create a symbolic link from clang to arm-linux-gnueabi-clang. Note that if your project uses C++, then you'd need to override CXX as well.
