Just an uneducated guess, but are you sure uclibc doesn't depend on HZ at all?
Some things might be just straight syscalls, others might be implemented in 
userspace (inside uclibc)... for example alarm(1) programming an alarm on 
jiffies+1/HZ, and HZ being compiled in from kernel headers ?
I may just be talking rubbish though.
