tools/configure: correct enable/disable-feature option

If --disable-feature is not specified then feature should default to n.
But with the current code disable with set feature to y, and enable will
set feature to n. Reverse the logic in the two .m4 files to use correct
default values.
The failure currently is that default := is y while it should be n.
