 * To impement gcc's stack protector library, the compiler emits a function call

 * we mimic what gcc does with libssp and create an archive file that can be
 * used in the specs file to pull this in directly. This is a bit of a pain, but
 * that's the best we can do given the architecture that we have.
 *
 * Warning: This is a static archive. Nothing beyond the call for
 * __stack_chk_fail_local and calls to committed interfaces should be here. As
 * this implementation will be linked into programs, one should exercise care to
 * make sure we don't expose anything else here.
