...having said that, looking at meson.build it looks like it
now ignores dtc's own Makefile and hardcodes how to build
libfdt, including a list of the source files. This seems
pretty fragile to me, but perhaps it means we don't care
any more about whether dtc's Makefile has the commit
85e5d839847a fix...
