I am using a Linux host with kernel version 4.x for cross building. It looks like autoconf is not defining the "PGRP_PIPE" macro variable as there is no check for linux kernel version 4. I don't see the error " child setpgid (4238 to 4232): Operation not permitted" after I backport this patch https://git.savannah.gnu.org/cgit/bash.git/diff/configure.ac?h=bash-4.4-testing&id=3bf257a5d95aa7d98d3da1a24be7b5b301716047 to bash-4.2
