It also forgets to include the usr/libexec/ld-elf32.so.1 symlink. I've changed the script to use a blacklist instead of a whitelist. Also, the 'find' invocation to purge empty directories from dist's in 'make release' did not work because the '-empty' predicate does not get "updated" when a subdirectory becomes empty as a result of rmdir deleting all its children. I've fixed that by having find delete the directories itself using -delete. This works properly as find can then notice that the directory is now empty.
