Yes. My point is that neither the GFDL (I think) nor the CC-by-sa
allows dual-licensed derivative works.

I'm afraid I just can't see how granting permission to use a work
under two different licenses makes it into two different works. If I
give you permission to enter my house through either the back door or
the front door, that doesn't mean I have two houses.

Is that supposed to be some kind of /reductio ad absurdum/? Maybe you
should take a closer look at the verbatim copying sections of both
licenses. Do either seem amenable to third parties distributing under
multiple licenses?
I realize that all this dual-licensing stuff seems counterintuitive,
but maybe we should instead be wondering why we would expect two
strong copyleft licenses to work well together in the first place.
Just because you have two good horses, doesn't mean you can ride them
both at the same time, with a foot on each one's back. One may be
taller than the other, or one may run faster than the other. Two
things that work well on their own may not work well together.
I don't think this is a hopeless case, by the way. I think you can do
a careful license grant that routes around the extreme exclusivity of
the two licenses. Maybe something like this:
"You may use this work per the terms of the Creative Commons
Attribution-ShareAlike 2.0 license or, at your option, under
the terms of GNU Free Documentation License 1.2. As a special
exception, you may also offer recipients of the work or
derivative works their choice of either of these two
licenses."
I don't think it's gruesome; I just think it takes some thought. I
don't see why that's some kind of radical nuthouse idea.
