  Log Message:
  -----------
  [PowerPC][PCRelative] Set TLS unsupported with PC relative memops

Introduce a fatal error if any thread local storage code is compiled
using pc relative memory operations as well as a hidden override
option `-enable-ppc-pcrel-tls` so that this support can be incrementally
added if possible.
