A little more info from my notes in case anyone is interested. YMMV and don't blame me if your views get trashed, but we haven't seen any problems with this approach:

To generate your own glibc for use by cleartool:

- extract the src (this is for RedHat)

mkdir my_glibc; cd my_glibc
rpm2cpio | cpio -iumd
tar jxf glibc-...-tar.bz2

- edit sysdeps/unix/sysv/linux/sleep.c to just return 0 if seconds==6

- make build dir within glibc-2.2... dir created by extract

- from within build dir, configure and make

cd my_glibc/glibc-2.2..../build ../configure --enable-add-ons=yes --without-cvs
make

- put the pieces together

mkdir ~/myct
cp my_glibc/glibc-2.2..../libc.so.X ~/myct

create a wrapper script to execute cleartool using this glibc:

#!/bin/bash
LD_LIBRARY_PATH=~/myct:$LD_LIBRARY_ PATH
exec cleartool ${*}

- use it

~/myct/ct update

Here's a stacktrace when cleartool is making the sleep call, showing that their sysutl_nfs_flush function is indeed calling a sleep(6), luckily I've overwritten the sleep(6) to return immediately:
