- The library files are now being built into the lib subdirectory of the source. - The linker files for each library are being copied into the lib source subdirectory. Motivation: The relative locations of files in the source directory after make are now the same as after make install now. This makes it easier to reuse examples with their makefiles outside of the libopencm3 sourcecode directory.
