I wonder if there is some package which is not yet ported to libtirpc and
requires Sun-RPC. Suppose yes, otherwise there wouldn't be that check, but I
haven't find any.

FYI openSUSE has been using libtirpc as a drop-in replacement for quite long
time. Maybe that could be a solution for Buildroot as well.

openSUSE change libtirpc.pc.in [1] in rpm spec file before build [1]:
sed -i -e 's|${includedir}/tirpc|${includedir}|g' libtirpc.pc.in
