I see the issue, you need the sparc32-chown patch in libc again.
The following should be debian/patches/sparc32-chown.dpatch and you should add sparc32-chown to the sparc section of the patches section in debian/rules.
#! /bin/sh -e
# All lines beginning with `# DPATCH:' are a description of the patch.
# DP: chown compat
if [ $# -ne 2 ]; then
echo >&2 "`basename $0`: script expects -patch|-unpatch as argument"
exit 1
fi
case "$1" in
-patch) patch -d "$2" -f -p1 < $0;;
-unpatch) patch -d "$2" -f -R -p1 < $0;;
*)
echo >&2 "`basename $0`: script expects -patch|-unpatch as argument"
exit 1
esac
exit 0
