No, you don't need LLVM runtime. You just need LLVM llc/opt if you'd 
like to cross-compile and build registerised ARM binaries.

If you'd like to use unregisterised /via-C binaries, then you don't need 
LLVM at all, you just need to configure with --enable-unregisterised 
IIRC, but I've not tested that so you are on your own.

Also it comes with its own performance penalty of course:
