    bsd.subdir.mk: Drop broken optimisation for realinstall parallelisation
    
    Not all of the tree is happy for realinstall to be done in parallel. In
    particular, Makefile.inc1 uses .WAIT to force etc to be installed after
    earlier subdirectories, since etc calls into share/man's makedb to run
    makewhatis on the tree and needs all manpages to have been installed.
    Also, libexec/Makefile doesn't set SUBDIR_PARALLEL, and the link from
    ld-elf32.1 to ld-elf.1 relies on rtld-elf having been installed before
    rtld-elf32, otherwise creating the link will fail.
    
    In general, core behavioural differences like this between NO_ROOT and
    "normal" builds are also dangerous and confusing.
    
    If this optimisation is deemed important, it should be reintroduced in a
    more limited and robust manner that doesn't break the above situations.
    Until then value correctness over slight efficiency gains on high core
    count machines, the same machines where you're more likely to encounter
    issues from this optimisation.
    
    This reverts commits cd19ecdbdc87 ("Similar to r296013 for NO_ROOT,
    force SUBDIR_PARALLEL for buildworld WORLDTMP staging.") and
    b9c6f3168112 ("Add more STANDALONE_SUBDIR_TARGETS.").
