commit 8525b870d5caa0a04858aa436ad6949ec277fc0c

    tap/awk: avoid redirection issues with bash 3.2 and earlier
    
    Fixes automake bug#10465.
    
    * lib/tap-driver.sh: Add workaround for bash 3.2 and earlier, which
    sometimes does not properly set '$?' when failing to write redirected
    output of a compound command.  See the Autoconf manual for more details.
    
    The workaround was pointed out by Eric Blake.
