When debugging hidden dependencies, the build order is very important.
Most notably, it is interesting to identify potential culprits.
Add a new top-level rule, show-biuld-order, that dumps all the packages
in the order they would get built.
Note that there are a few differences with show-targets:
- more packages are reported, becasue show-targets does not report
host packages that have no prompt;
- the output is line-based, because we're using $(info $(1)); getting
a single output line like show-targets would require we use an
actual command, like printf '%s ' $(1); but that takes a lot of
time, while $(info $(1)) is almost instantaneous (the time to parse
the Makefiles);
- rootfs targets are not reported.
