If they want dependence tracking, yes.  Note that it will be enabled
by default if it can be obtained as a side effect of compilation.
Also note that, if the dependence file is a generated file that is not
part of the distribution, simply enabling dependence tracking won't be
enough: when make decides to build the file, it doesn't know yet what
its dependences are.  Dependencies on generated files must be
explicitly encoded in the Makefile, except for BUILT_SOURCES, that
automake takes care of building by itself.
