when building dtc/libfdt, we were previously using dtc/Makefile,
which tries to build some artifacts that are not needed,
and can complain on stderr about the absence of tools that
are not required to build just libfdt.
Instead, build only the strict necessary to get libfdt.a .
Remove the subdir-dtc "compatibility gunk" for recursion,
since we are not recursing anymore.

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.

I'm getting:
config-host.mak is out-of-date, running configure
make: *** No rule to make target 'dtc/all', needed by 'config-host.h'.
Stop.
On second try it works.
Instead of alarming users, we could keep this target as a silent no-op,
then remove it after some time.
For the rest, patch looks good, nice cleanup!
Regards,
Phil.

FYI same happens when going back (previous this patch applied) but there
is nothing we can do to prevent that afaik:
config-host.mak is out-of-date, running configure
make: *** No rule to make target 'libfdt', needed by 'config-host.h'. Stop.

hmm maybe preserving the previous name for the phony rule "dtc/all" could make it work both forward and backward..
I'll try it in v3.

I am tempted to remove the old compatibility gunks that are marked as "to be removed some time after 4.1" as the second patch in the series,
any thoughts? (Markus?)
