+Fix usage of gdlib-config
+
+gnuplot configure.in script properly takes care of finding
+gdlib-config using AC_PATH_PROG... but then directly uses gdlib-config
+instead of going through the GDLIB_CONFIG variable that AC_PATH_PROG
+has defined. Which means that whenever a gdlib-config binary not in
+the PATH is being used, it does not use it.
