Title: Prevent 'command not found' if rustc is not yet installed

If rustc is not yet installed, output looks like:

$ make nightly-install
/bin/bash: rustc: command not found
/bin/bash: rustc: command not found
...
Rust install-script stored as '~/rustup.sh'

I believe this doesn't have any side effect?
