how to get rid of libcrypto?

I compiled net-snmp 5.3.0.1 for linux, with -disable-privacy. Basically I
don't need v3 mibs or any of the encryption stuffs. I just need a simple
snmp v2c agent.  And my space is really limited. How can I get rid of
libcrypto.so, libkrb.so etc. So that they don't need to be loaded at
runtime? I tried -disable-privacy which suppose to disable encryption. But
it doesn't work. Any other thing I can do? Thanks.
