To solve the issue of carrying object files from previous builds,
Matias changed the archiving process to re-archive libapps.a on every compilation,
if libapps.a carries more object files, incremental compilation will waste too
many time in re-archiving, compared with the previous implement, this is a degradation
of the build system. Referring to mature engineering projects such as cmake, if there
is configuration or source file changed, the best solution should be to reconfigure
the environment.
Revert this PR to ensure the compilation speed during incremental compilation.

|
| Fix: ensure archive files do not carry object files from prior builds
|
| This is the corresponding change to the one on main NuttX repo. In this
| case this involves splitting the build of libapps.a into: a) building
| all applications (which is safely parallelizable), b) adding each
| application's object files to the archive in turns (serial by nature).
|
| This removes the need for the flock used to protect the parallel build.

The mqttc demo under example path can not support mbedtls api.
Because of the MQTT-C source code already contains many types of
link examples, so we added the corresponding makefile to
support mbedtls mqttc connections publisher and posix mqttc
connections publisher and subscriber.
