title: How do I use custom assembler for clang?
body: <p>I've compiled clang to use it as a cross compiler for ARM (by configuring it with <code>./configure --target=armv7l-unknown-linux-gnueabihf</code> ), but when I try to compile any C code, it tries to use <code>/usr/bin/as</code>. I already have binutils compiled for ARM, and they are in a separate directory. How do I direct clang (or llvm) to use the assembler that I specify?</p>
