The hacks that rely on features specific to GNU Make
should be disabled if --no-assume-gmake was set.

To handle that situation, if --assume-gmake is not set, then you could
either just drop that dependency, or add it unconditionally.

Presuming you make the change suggested above, that should be
"When generating @file{.d}, @file{.dv}, and @file{.dep} files, ...".

Otherwise, that change looks fine -- thanks.
