That usually means a new make is started without the calling make
realizing it is starting a make. In most of the cases that means that
some makefile (like debian/rules) is calling make instead of $(MAKE).

There are also some special other cases (like when $(MAKE) is used, but not
directly but indirectly referenced, then this might be fixed by
prefixing the command with a +, but beware of the other meanings this
has.), which normally dictate a closer look, as when something is doing
such absurdities, there might be some reason to it. (well, or not)
