This patch removes the implicit build of all shared libraries a target depends on. Targets only depend on the respective ABIs instead. This alleviates the need to locally build complex shared libraries (think of Qt) when developing applications. Instead, application developers can use binary depot archives. The implementation splits the mk/lib.mk file into three files: - mk/a.mk for building one static library (.lib.a) - mk/so.mk for building one shared object (.lib.so) - mk/abi.mk for building one ABI stub (.abi.so) Furthermore, the commit moves messages and the collection of build artifacts to var/libdeps, triggers the build of kernel-specific ld-<kernel>.lib.so, and prunes the lib-dependency tree at ABIs. Fixes #5061
