Yep. debian-installer dailies are now *dead* until we get a modern libc
working.

I wonder whether there are debian source packages for binutils, gcc and 
glibc having TLS/NPTL support for m68k.

The patches posted to the binutils mailing list are incomplete. The 
binutils patch at
http://people.debian.org/~smarenka/m68k/tls/
is broken according to Kolla:
http://lists.debian.org/debian-68k/2009/07/msg00001.html

But in that post (June 28) Maxim recommends using mainline binutils, and 
since then we have HJL binutils-2.19.51.0.14 released, "...based on 
binutils 2009 0722 in CVS on sourceware.org..." So I guess I should start 
there.

I understand that the current GCC (4.4) lacks the necessary patches, and 
4.5 is still uncooked (and that's a scary prospect). Can someone confirm 
that this is the necessary patch for 4.4:
http://gcc.gnu.org/ml/gcc-patches/2009-05/msg01024.html
Presumably not this one?
http://people.debian.org/~smarenka/m68k/tls/gcc_patch2
(and gcc_patch1 is clearly broken... perhaps it was actually the same 
thing before being mangled... Stephen, I don't think this "/tls" directory 
is helping any.)
Or perhaps there is a known-good gcc 4.5 snapshot (FWIW, I'd much rather 
patch a debian compiler instead, which means 4.4 or preferably older.)

As for eglibc, there are a number of branches listed here, 
http://www.eglibc.org/repository
The question is, which branch, snapshot or release might meet be suitable?

With this information, I could attempt to build a toolchain from upstream 
sources, or figure out whether or not the debian archive has the necessary 
source packages...
