One should be able to do a cross build of the libc now. For example, using clang on a x86_64 linux host, one can build for an aarch64 linux target by specifying -DLIBC_TARGET_TRIPLE=aarch64-linux-gnu. Follow up changes will add a baremetal config and also appropriate documentation about cross compiling the libc for CPU targets.

libc Documentation ================== The libc documentation is written using the Sphinx documentation generator. It is currently tested with Sphinx 1.1.3. To build the documents into html configure libc with the following cmake options: * -DLLVM_ENABLE_SPHINX=ON * -DLIBC_INCLUDE_DOCS=ON After configuring libc with these options the make rule `docs-libc-html` should be available.
