Here are two patches to bring these files over from libgcc, the first
copying the files verbatim and the second making the copyright and
license notices match current glibc practice. (Presume that
<https://sourceware.org/ml/libc-alpha/2013-10/msg00353.html> would
also be updated to cover the new files.)
