I suppose this still won't work yet because Binutils is not fully fixed.
GAS has been changed not to emit R_LARCH_RELAX for "la.tls.ie a0, t0,
foo", but ld is still not checking if an R_LARCH_RELAX is after
R_LARCH_TLS_IE_PC_{HI20,LO12} properly. Thus an invalid "partial" TLS
transition can still happen.
