ldconfig seems no functional under alpine 3.3
<p>I'm currently install the goczmq (<a href="https://github.com/zeromq/goczmq" rel="noreferrer">https://github.com/zeromq/goczmq</a>) on golang:1.6.2-alpine docker container, as following:</p>

<pre><code>wget https://download.libsodium.org/libsodium/releases/libsodium-1.0.10.tar.gz
wget https://download.libsodium.org/libsodium/releases/libsodium-1.0.10.tar.gz.sig
wget https://download.libsodium.org/jedi.gpg.asc
gpg --import jedi.gpg.asc
gpg --verify libsodium-1.0.10.tar.gz.sig libsodium-1.0.10.tar.gz
tar zxvf libsodium-1.0.10.tar.gz
cd libsodium-1.010.
./configure; make check
sudo make install
sudo ldconfig
</code></pre>

<p>The process failed on <code>ldconfig</code>, there seems be a command <code>ldconfig</code>, but  I don't think it is actually functional. Any insights? Thank you in advance. </p>
