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.
