I have a securely generated private key that I want to use to generate an ethereum address on an offline PC (Ubuntu 32 bit). My preferred way would be to use geth, but there's no geth binary for linux 32 bit. My questions are:

Why there are no 32-bit binaries available? What are the alternative ways to generate an ethereum address (binaries preferred) except MyEtherWallet? What happens if I try to run 64-bit geth on 32-bit Linux?
