    help.mk, clean.mk: drop __frontend for tty test · ec3d40cc
    Michael Shigorin authored
    The __frontend variable was introduced to address the needs
    of alterator-mkimage module: list the images available in
    one column, purge the builddir.
    
    Looks like we should consider other cases with redirected
    stdout (cron builds, piped calls, etc) like fundamentally
    non-interactive and behave the same.
    
    So commit 3a8af6b5's
    description is wrong now; the current cleanup rules are:
    
    - if CLEAN=0 or DEBUG>1, don't do it;
    - if CHECK or REPORT is set, don't do it;
    - otherwise if at least one of the following conditions is true:
      + there's more than one target being built in a row;
      + stdout was redirected (cronjob, alterator-mkimage...);
      + metaprofile directory is read-only
      ...then do a distclean.
    
    If that doesn't suit your needs, describe the particular
    situation please.
    
    Thanks cas@ for wondering aloud whether greppable output
    is unsupported with `make help'.
