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
|
| In some cases, when NuttX configuration changes and this makes the
| object list used to build one of the .a libraries change as well,
| since the command used to build it is "ar crs" and this simply appends
| the list of object files, the library could still include object
| files from prior builds. This commit modifies the ARCHIVE macro to
| erase the .a file if it already exists.
|
| Since in some cases this behavior was actually expected (object
| files from a subdirectory were appended to a library created one
| level above) I added a ARCHIVE_ADD which works as ARCHIVE did.
|
| This change should greatly improve behavior of building after
| configuration changes.

Add PREBUILD definition and `prebuild` recipe to call it before
the `mkconfig` tool, at the beginning of the build process. This
`prebuild` step enables running CPU/board-specific operations
before building the firmware, like tweaking or overriding configs
that need to be set after the board configuration.
Summary:
- I noticed that the following build error happened on my machine.
make -C sched libsched.a EXTRAFLAGS="-D__KERNEL__ "
make[1]: Entering directory '/mnt/m2ssd/opensource/RTOS/tmp/nuttx/sched'
/bin/sh: 1: echoCC: clock/clock_initialize.c : not found
- This commit fixes this issue
Impact:
- Should be none
Testing:
- Build on ubuntu 18.04 x86_64

Using the full path will make __FILE__ longer, which will lead to a larger flash footprint

In order to make compilation warnings and errors easier to be found out,
this commit will disable the printing of the compilation process as much
as possible, and also if you want to restore the log information of the
compilation process, please enable verbose build on command line:
$ make V=0
OR
$ make V=1
| V=0: Exit silent mode
| V=1,2: Enable echo of commands
| V=2: Enable bug/verbose options in tools and scripts

In the past, header file paths were generated by the incdir command
Now they are generated by concatenating environment variables
In this way, when executing makefile, no shell command will be executed,
it will improve the speed of executing makfile

## Summary
A lot of linker scripts were listed twice, once for unix, once for windows.
This PR cleans up the logic so they're only listed once.
## Impact
Any opportunity to use a single source of truth and reduce lines of code is a win!
## Testing
CI will test all build
Use `JLinkGDBServer -rtos libnuttxplugin` to add this plugin.
Then in gdb can use command:
- `info threads` to show all threads infos
- `thread (id) ` to switch thread.
- `bt` to show thread backtrace.
