During each make run, the build system checks that any specified
dependencies
do actually exist, to prevent typos and other errors from fouling up
correct
dependency settings. However, it also causes make to trip up when new
components have been added to the code, but not yet registered in the
build
system by configure. A manual configure call is required in this case.
The "config" target is designed precisely to reinitialize the build
without
having to manually call configure. Skip the dependency check when
running
the "config" target to allow automatic reconfiguration in such cases.
Also skip the dependency check when doing clean, distclean and
fate-rsync.

Another less backwards way of writing this probably would be
ifneq ($(filter-out clean config distclean fate-rsync, $(MAKECMDGOALS)), )
I can amend it to that if you prefer that version.
This version looks better IMHO.
