I don't think it would be a cross compiling. The main difference
between llvm and gcc backend is that llvm directly support generating
code for different target while in gcc you have to cross compile.
Cross compiling for llvm means "create LLVM executables and libraries
to be hosted on a platform different from the platform where they are
build (a Canadian Cross build)" based on the llvm documentation.

I was just curious now that llvm supports that many targets, how
should users deal with libraries of those targets?
