Yes, the assembler output here should be "bl\\t%c0(tlsdesc)" for all
variants.

I'd also much prefer that the named variant be GNU and GNU2, as they are
for x86.  It's much less confusing to users that way (the fact that the
first (GNU) variant is documented in the ARM ABI specification is simply
down to a lack of external documentation to refer to, but the underlying
model is the same as that used elsewere for the first GNU version).
