v2 -> v3:

* changed into a 2 patch series; in the second patch we remove the old
  compatibility gunks that were meant for removal some time after 4.1.

* renamed the libfdt PHONY rule to dtc/all, with the intent to make
  existing working trees forward and backward compatible across the change.

v1 -> v2:

* fix error generated when running UNCHECKED_GOALS without prior configure,
  for example during make docker-image-fedora. Without configure, DSOSUF is
  empty, and the module pattern rule in rules.mak that uses this variable
  can match too much; provide a default in the Makefile to avoid it.

* only attempt to build the archive when there is a non-empty list of objects.
  This could be done in general for the %.a: pattern in rules.mak, but maybe
  there are valid reasons to build an empty .a?

* removed some intermediate variables that did not add much value
  (LIBFDT_srcdir, LIBFDT_archive)

Tested locally with 3 VPATH configurations (no-, VPATH, VPATH in src subdir),
and with docker-image-fedora, docker-test-debug@fedora that failed before.
