build: adjust warning options to work with latest GCC
* configure.ac: Disable some new warnings to avoid false positives.
Building with warnings enabled and latest gcc would evoke build
failure without these changes. Disable the following in coreutils
proper: -Wformat-overflow=2 -Wformat-truncation=2, and
disable these for gnulib: -Wformat-truncation=2 -Wduplicated-branches
