Norman Feske 9aab61f5a7 mk: allow declaration of build artifacts for libs
The build system automatically announces the names of shared libraries
as build artifacts. However, in rare cases, it is required to manually
define them. In particular, the 'ld' stub library plays no role at runtime
and should not be integrated into the boot image.

This patch adds a customization hook following the same pattern as used
for target.mk files, namely the BUILD_ARTIFACTS variable. If defined,
its value is taken as the list of boot artifacts generated by the
library-description file.

..

This directory contains the build system. In consists mainly of makefile
templates for different directory roles.

:'global.mk': This file contains global variables, for example the
  definitions of the tools to use.

:'generic.mk': Generic rules for creating file types from others.

:'prg.mk': This file represents the target binary role of a directory.
  It must be included by all makefiles that build programs.

:'lib.mk': This file represents a library role. It is never used from
  within the 'src/' directory but only from the <libname>.mk files
  in 'lib/mk/'.
