@item distclean-stage@var{N} (@var{N} = 1@dots{}4, profile, feedback)
Wipe stage @var{N} and all the following ones.
For example,

but a full @command{make restrap} isn't necessary either.
@item profiledbootstrap
Builds a compiler with profiling feedback information. In this case,
the second and third stages are named @samp{profile} and @samp{feedback},
