Here's the final version, which matches what is in binutils. It has
changed slightly since the previous submission, since the tile gcc
maintainer and I worked out a somewhat better (forward-looking) model
for TLS support. (In particular, we now support IE directly, and are
prepared to do the work to support LE transparently when we get the
time to spend on it.)

* elf/elf.h: Include Tilera machine types and relocation values.
