    tmac/tmac.am: Remove unidiomatic for loop.
    
    * tmac/tmac.am ($(TMACSTRIPFILES)):
      ($(TMACMDOCSTRIPFILES)): Remove unidiomatic for loop which frustrated
      parallel make operation.
    
    Thanks to an anonymous contributor for the report and patch.
    
    Fixes <https://savannah.gnu.org/bugs/?59958>.
    
    The bug report characterizes the for loop as a "race", which I don't
    think is strictly correct, since the outcome of the work done is not
    subject to variation.  The body of the for loop is a clobbering shell
    redirection operator, so the problem was one of potential pointless
    repetition of work in concurrent operation.  Good to fix, but not a
    cause for alarm.
    
    Problem dates back to 2609cfb727a98809548edfd721c5cb923085b24b, 6
    September 2014.
