Add a makefile for updating the files in this directory.

sql/GNUmakefile

+#
+# This makefile is different than all the others...
+# 
+# It is intended to be run in place in the cvs tree to update the files,
+# and doesn't install or build anything else. This is why it doesn't go
+# through configure, etc.
+#
+
+# The easy way: do 'gmake all'
+# You can also run the individual targets too.
