Thanks! Pushed as e8b409741baf3b9de30faa8683722375196dd1e9 after
removing this comment about test inputs:

I removed it after checking the references of the built package like
this:

------
$ guix gc --references $(./pre-inst-env guix build rct)
/gnu/store/3h31zsqxjjg52da5gp3qmhkh4x8klhah-glibc-2.25
/gnu/store/6wyjls0q2c9gjskkplsr1ad09p3d8gzg-gcc-5.4.0-lib
/gnu/store/navpkpm1jf6zf8zmi54wl5w3b2ddv1sw-zlib-1.2.11
/gnu/store/nl3zjmg4wv40j8sv1fhla1g1ngysd8nq-openssl-1.0.2n
/gnu/store/w8ypl7zfs4q8cqc9k8k61q4dx69l770h-rct-0.0.0-1.b3e6f41
------

We can see the built package refers to some of those inputs and thus may
use them at run-time. So, the comment is not totally accurate (and not
strictly required).

And I got curious, so I tried something like this:

------
$ grep -r /gnu/store/nl3zjmg4wv40j8sv1fhla1g1ngysd8nq-openssl-1.0.2n $(./pre-inst-env guix build rct)
Binary file /gnu/store/w8ypl7zfs4q8cqc9k8k61q4dx69l770h-rct-0.0.0-1.b3e6f41/lib64/librct.so matches
/gnu/store/w8ypl7zfs4q8cqc9k8k61q4dx69l770h-rct-0.0.0-1.b3e6f41/lib/cmake/rct-relwithdebinfo.cmake:  IMPORTED_LINK_INTERFACE_LIBRARIES_RELWITHDEBINFO "pthread;/gnu/store/navpkpm1jf6zf8zmi54wl5w3b2ddv1sw-zlib-1.2.11/lib/libz.so;/gnu/store/nl3zjmg4wv40j8sv1fhla1g1ngysd8nq-openssl-1.0.2n/lib/libcrypto.so;dl;rt"
------

I saw that librct.so refers to both OpenSSL and zlib, so I made them
regular inputs in the followup commit
bad12e839c2f7823c45aa0121f7d5c9bb70905b7

I should have checked before pushing :)
