HTK 32bit issue -> apt-get install gcc-multilib ->"Package 'gcc-multilib' has no installation candidate"

I am trying to install HTK. I tried ./configure, and received an error on make all:

cd HTKLib && 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.cIn 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 <bits/libc-header-start.h>

So I searched this issue, and found "fatal error: bits/libc-header-start.h: No such file or directory" while compiling HTK. This led to the following solution sudo apt-get install gcc-multilib. However, this gives another issue:

Reading package lists... DoneBuilding dependency tree       Reading state information... DonePackage gcc-multilib is not available, but is referred to by another package.This may mean that the package is missing, has been obsoleted, oris only available from another sourceE: Package 'gcc-multilib' has no installation candidate

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.
