I believe it's

commit b4e61f85ae26d215e8ad5d6e9fcda6c0745096a1
Author: Richard Biener <address@hidden>
Date:   Fri Jul 6 21:35:29 2018 +1000

            * lib/remote.exp (close_wait_program): Use separate kill command
            for each pid.

Richard pointed me at the 1.6.2 release when I mentioned the issue
somewhere on a gcc list, and it's his patch, so it's likely to be the
one.

It went into DejaGnu immediately after the 1.6.1. release ;-(
