Yes, but not via __thread.  I wrote a small program that sets
the TLS pointer to an arbitrary value (via MIPS_SET_TLS),
then issued rdhwr instruction using C inline assembly, and
finally verified that both values are the same.

(the toolchain I'm using doesn't support __thread either,
but I submit this patch with the expectation that it can be
useful later on)
