Build failed for checkinstall due to lack of support of iconv

Description :

We are building checkinstall, using the below command

git clone {url}
git checkout master
git pull origin
make PREFIX=/opt/ CONFDIR=/opt/etc/checkinstall

I got below error while running this command "make PREFIX=/opt/ CONFDIR=/opt/etc/checkinstall"

#0100/002-11 | make PREFIX=/opt/ CONFDIR=/opt/etc/checkinstall
----------------------------------------
for file in locale/checkinstall-*.po ; do \
	if [ "${file}" != "locale/checkinstall-template.po" ]; then \
		out=`echo "$file" | sed -s 's/po/mo/'`; \
		/usr/bin/iconv  -f ISO-8859-15 -t UTF-8 "$file" -o "$file".utf8 || exit 1; \
		msgfmt -o "$out" "$file".utf8 || exit 1; \
		rm -f "$file".utf8; \
	fi; \
done
msgfmt: Cannot convert from "ISO-8859-15" to "UTF-8". msgfmt relies on iconv(). This version was built without iconv().
make: *** [Makefile:13: all] Error 1
----------------------------------------

Could someone help identify the cause of this issue and suggest a solution? Any guidance or help would be greatly appreciated.
