sivachandra requested review of this revision.

One should be able to do a cross build of the libc. For example, using
clang on a x86_64 linux host, one can build for an aarch64 linux host by
specifcy -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.
