At least for Hurd, it looks like Debian's libc addresses your problem.
According to /usr/share/doc/libc6/changelog.Debian.gz:
glibc (2.5-5) unstable; urgency=low
[...]
[ Michael Banck ]
* patches/hurd-i386/local-dl-dynamic-weak.diff: new patch (turn
_dl_dynamic_weak on by default for hurd-i386).

That doesn't help libpthread-stubs, though. And if, as the bug you
referenced says, the ELF standards don't specify the behavior we expected
for weak symbols, I don't know that we have a solution.
