ac1447ae9d build: Rebuild libs all the time
When files change that go into a static library such as libutils.a, then
libutils.a doesn't get rebuilt from, e.g., wlantest because the
top-level Makefile just calls the library make if the library doesn't
exist yet.

Change that by making the library depend on a phony target (cannot make
it itself phony due to the pattern) so that the build will always
recurse into the library build, and check there if the library needs to
be rebuilt.

While at it, remove the (actually unnecessary) mkdir so it doesn't get
done each and every time you do 'make'.

87098d3324 build: Put archive files into build/ folder too
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.

ce963433bd build: Allow overriding BUILDDIR from command line
You can now specify BUILDDIR= on the make command line,
e.g., in order to put that into a tmpfs or similar.

6acda53222 build: Add .config file to dependencies
If the .config file changes, basically everything needs to be
rebuilt since we don't try to detect which symbols changed or
such. Now that the .config file handling is in the common
build system, make everything depend on it if there's one.

722138cd25 build: Put object files into build/ folder
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.

0464d5d5d6 build: Move config file handling into build.rules
This will make it easier to split out the handling in
a proper way, and handle common cflags/dependencies.

0430bc8267 build: Add a common-clean target
Clean up in a more common fashion as well, initially for ../src/.

Also add $(Q) to the clean target in src/

Some things are used by most of the binaries, pull them
into a common rule fragment that we can use properly.
