v4 -> v5:
* include the dtc submodule update commit in the 1/2 patch
v3 -> v4: NB! only useful when updating to latest dtc (not in QEMU yet)
* changed the approach to leverage new upstream dtc Makefile,
needs dtc submodule update to include upstream dtc commit
85e5d839847af54efab170f2b1331b2a6421e647.
* LIBFDT_srcdir does not exist anymore in upstream dtc: it is also
not used anymore.
* LIBFDT_lib: need to avoid building libfdt.so at least for now, so pass as
empty to avoid building the .so. This is to avoid breaking existing
trees with objects already compiled without -fPIC.
* clean: no need to make dtc clean target, every artifact is captured by
global clean rule
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.
