That gcc on there is before the gotdata support got added, nevermind.

Ok, that's a good data point.

Try this, declare the table as:

        .section        ".rodata"
	.type		ctz_table,#object

Because I'm beginning to suspect that the linker isn't lying to us,
and the assembler is emitting ctz_table in section STT_TLS for some

And that this has been happening all along.  Perhaps if you don't
declare an object's type it gets some default, and in this case the
default ends up being #tlsobject.

If this is the case, it's simple to deal with this this by simply
using ".type" directive consistently.

I can do all of the grunt work once you confirm this.
