Namely the secure rpc key generators, the secure diffie hellman rpc key exchange, and telnet SRA key exchange at startup. None of these use it more than once (or once per connection). telnet is already linked against libcrypto. It should be using that for bignum support instead of libmp. libmp is dead. libcrypto is the interface of choice to use these days, or libgmp. Nothing in our tree uses libgmp.
