gnutls requires a configuration file, and the configuration file must match
the one used by the library. Since we ship our own version of the library with
the relocatable package, we must also ship the configuration file.
Luckily, it is possible to override the location of the configuration file via
an environment variable, so all we need to do is to copy the file to the archive
and provide the environment variable in the thunk that adjusts the library path.
