title: HTK 32bit issue -> apt-get install gcc-multilib -> "Package 'gcc-multilib' has no installation candidate"
body: <p>I am trying to install HTK. I tried ./configure, and received an error on <code>make all</code>: </p>
  
  <pre><code>cd HTKLib &amp;&amp; make HTKLib.a) \
    || case "" in *k*) fail=yes;; *) exit 1;; esac;
  make[1]: Entering directory '/home/pranay/HTK-3.4.1/htk/HTKLib'
  gcc  -m32 -ansi -D_SVID_SOURCE -DOSS_AUDIO -D'ARCH="x86_64"' -Wall -Wno-switch -g -O2 -I. -DPHNALG   -c -o HGraf.o HGraf.c
  In file included from HShell.h:40,
                   from HGraf.c:54:
  /usr/include/stdio.h:27:10: fatal error: bits/libc-header-start.h: No such file or directory
     27 | #include &lt;bits/libc-header-start.h&gt;
  </code></pre>
  
  <p>So I searched this issue, and found <a href="https://stackoverflow.com/questions/54082459/fatal-error-bits-libc-header-start-h-no-such-file-or-directory-while-compili#">&quot;fatal error: bits/libc-header-start.h: No such file or directory&quot; while compiling HTK</a>. This led to the following solution <code>sudo apt-get install gcc-multilib</code>. However, this gives another issue: </p>
  
  <pre><code>Reading package lists... Done
  Building dependency tree       
  Reading state information... Done
  Package gcc-multilib is not available, but is referred to by another package.
  This may mean that the package is missing, has been obsoleted, or
  is only available from another source
  
  E: Package 'gcc-multilib' has no installation candidate
  </code></pre>
  
  <p>I was unable to find a proper solution after this point. I could try to remove -m32 from the file originally, but apparently this is not the proper way and could lead to more issues. </p>
