Thanks for those. I was actually referring to building glibc-2.5.x.
Hopefully, your host's glibc shouldn't be affecting things by that

A little Google on "glibc cleanup handler not called for 'read'" got
me what I wanted.

Apparently, enabling CONFIG_COMPAT_VDSO on linux-2.6.18 causes a lot
of failures for glibc's testsuite. Can you check if your kernel has
that set? If so, then we know the problem. Then, you can either assume
that the failures are just due to the environment and continue (safe,
IMO). Or, you can build a new kernel for Etch with CONFIG_COMPAT_VDSO
off and try running the glibc tests again.

Of course, if the issue isn't CONFIG_COMPAT_VDSO, then there's some
more digging.
