commit eec6ab399159b8c3caec722d956531a4e799a84c
Author: Jim Meyering <address@hidden>
Date:   Mon Dec 5 04:15:24 2016 -0800

    tests: use just-built grep in more places
    
    * cfg.mk (PATH): Prepend $(srcdir)/src, so that we use the just-
    built grep also when running commands like those of "make distcheck".
    This would have avoided the recently-luckily-noticed infloop bug.
    Tested by running this in a just-built directory:
    f=src/grep; printf '%s\n' '#!/bin/sh' 'sleep 9h' > $f; chmod a+x $f
    and then verifying that nearly every "make syntax-check" rule hangs.
