We normally get the list of builtin commands by expanding BUILTIN_OBJS. But for commands which are embedded inside another's source file (e.g., cmd_show() in builtin/log.c), the Makefile needs to be told explicitly about them. Since cmd_maintenance() is inside buitin/gc.c, it should be listed explicitly in the BUILT_INS list in the Makefile. Not doing so isn't _too_ tragic, as it simply means we will not make a git-maintenance symlink in libexec/git-core. Since we encourage people to use the "git foo" form, even in scripts which have put libexec into their PATH, nobody seems to have noticed.
