Summary
Add
Library.mkfor shared libraries declared withLOCAL_MODULEandLOCAL_SRC_FILES. Convert thesotestmodules and split the exportedmessages into a second source file to cover multi-source builds.
The helper supports C and C++ sources and per-module build flags. Compiler
runtime lookup is shared with
Application.mkthrough one Make helper.Documentation: apache/nuttx#19888
