It looks like configure detected the reallocarray() function in the C library but its prototype is not present in the header files. This could be due to an out of date libc6-dev package (or the equivalent). Alternately, if you ran configure on the host system but are building in the proot that would also explain it. Either way, I don't think this is a problem with sudo itself.

Closing, sudo builds successfully on the latest Debian
