The objs.mk include changes for archive files broke things
completely and none of the dependency files (*.d) ever got
included, as the expansion there ended up empty.
Clearly, my mistake, I should've tested that better. As we
don't need the %.a files in the list there use filter-out
to remove them, rather than what I had lazily wanted to do,
which was trying to read %.d files for them. The filter-out
actually works, and avoids looking up files that can never
exist in the first place.

This is something I hadn't previously done, but there are
cases where it's needed, e.g., building 'wlantest' and then
one of the tests/fuzzing/*/ projects, they use a different
configuration (fuzzing vs. not fuzzing).
Perhaps more importantly, this gets rid of the last thing
that was dumped into the source directories, apart from
the binaries themselves.
Note that due to the use of thin archives, this required
building with absolute paths.

Instead of building in the source tree, put most object
files into the build/ folder at the root, and put each
thing that's being built into a separate folder.
This then allows us to build hostapd and wpa_supplicant
(or other combinations) without "make clean" inbetween.
For the tests keep the objects in place for now (and to
do that, add the build rule) so that we don't have to
rewrite all of that with $(call BUILDOBJS,...) which is
just noise there.
