I did this change for openssl@1.1.0 (attached). The 'config(ure)' script
now takes a -rpath flag which works as advertised.

However by duplicating the 'configure' phase, I discovered that the
'version' variable actually gets the inherited value when using
'substitute-keyword-arguments', and had to duplicate the
'remove-miscellany' phase as well, since it tried deleting a directory
called '$out/share/openssl-1.0.2j'. Should I file a bug for this, or
is it something intrinsically unfixable?

Subject: [PATCH] gnu: openssl-next: Update to 1.1.0c [fixes
 CVE-{7053,7054,7055}].

* gnu/packages/tls.scm (openssl-next): Update to 1.1.0c.
[arguments]: Duplicate 'configure' to add rpath flag previously handled by
now-defunct 'patch-runpath' phase. Duplicate 'remove-miscellany' phase.
