add Makefile.judging for IOCCC judging use

Added `template/entry/Makefile.judging`, a Makefile that is
similar to `next/Makefile.example` except that it is
more suitable for IOCCC judging, especially during
the final rounds of judging.

+# NOTE: The IOCCC Judges recommend you leave CC as just "cc"
+#       and NOT set it to clang, or gcc, or something else
+#       unless you have a STRONG reason to do so.
+#
+#       Setting CC to something other than "cc" makes your
+#       code less portable to those who do not have your
+#       particular C compiler.  **hint**
+#
+#       If you want to test your code with a particular C compiler,
+#       use the make command line.  For example:
+#
+#           make all CC=clang
+#           make all CC=gcc
+#
+CC= cc
+
+# Compiler add-ons or replacements for clang only
+#
+ifeq "$(findstring $(CLANG),${CC})" "$(CLANG)"
+#
+# NOTE: This code is only invoked when CC is "clang"
+#       such as when you use the make command line:
+#
+#           make all CC=clang
+#
+CSILENCE+=

+CWARN+= -Weverything

+# Specific add-ons or replacements for gcc only
