This was fixed in a string of commits leading up to r154304 which implemented
the final optimization for these types of global references. Clang now produces
the exact same output as GCC for these test cases.

There may well be non-TLS constructs which would benefit from special treatment
in -fpie as opposed to -fpic. Please file separate PRs with test cases as you
find them.
