Well, it's not really needed, but we will have less warnings in the config.log
file, which is a great help IMHO to identify real problems.
[issues:#5618] configure: Fix tests for compiler warning flags.

AC_LANG_PROGRAM
ignores compiler warnings. This behaviour made the tests
always true and thus without any effect. We now add -Werror
to enforce an
error in case the warning flag is not known.
To make that work it is also necessary to compile confdefs.h
without
warnings; we add a hack to undefine macro PACKAGE_NAME
, which gets defined
twice for historical reasons.
