New description:

 When not using the universal variant, zstd will link with libz, liblz4 and
 liblzma if they are present:

 {{{
 $ port deps zstd
 zstd @1.3.4_0 has no dependencies.
 $ otool -L /opt/local/bin/zstd
 /opt/local/bin/zstd:
         /opt/local/lib/libz.1.dylib (compatibility version 1.0.0, current
 version 1.2.11)
         /opt/local/lib/liblzma.5.dylib (compatibility version 8.0.0,
 current version 8.4.0)
         /opt/local/lib/liblz4.1.dylib (compatibility version 1.0.0,
 current version 1.8.2)
         /usr/lib/libSystem.B.dylib (compatibility version 1.0.0, current
 version 1238.60.2)
 }}}

 The zstd port should declare dependencies on the zlib, lz4 and xz ports
 and make their use explicit via configure args.

 Or, if the use of these libraries is not desired, the port must ensure
 they are not used, even if they are installed.

 Whichever solution is chosen, the `revision` will need to be increased.
