Enabled sectioned compilation for the plugin library, and linking with garbage collection for the plugins. The effect is that functions and data objects from one object file in the plugin library are included in the .elf individually, not as a whole. It makes maintaining larger plugin library packages easier, as it is no longer necessary to split the source files by function to avoid dead code to get included in the plugins.
