The <build-dir>/bin/ directory used to contain symbolic links to the unstripped build results. However, since the upcoming depot tool extracts the content of binary archives from bin/, the resulting archives would contain overly large unstripped binaries, which is undesired. On the other hand, always stripping the build results is not a good option either because we rely of symbol information during debugging. This patch changes the installation of build results such that a new 'debug/' directory is populated besides the existing 'bin/' directory. The debug directory contains symbolic links to the unstripped build results whereas the bin directory contains stripped binaries that are palatable for packaging (depot tool) and for assembling boot images (run tool).
