Thanks for the prompt fix, just from visual inspection it looks good,
but just in case:

[perfbuilder@...co ~]$ dm debian:experimental-x-{arm64,mips,mips64,mipsel} fedora:{24-x-ARC-uClibc,30-x-ARC-{g,uC}libc} 
   1   debian:experimental-x-arm64   : Ok   aarch64-linux-gnu-gcc (Debian 8.3.0-7) 8.3.0
   2   debian:experimental-x-mips    : Ok   mips-linux-gnu-gcc (Debian 8.3.0-7) 8.3.0

[perfbuilder@...co ~]$

So I merged this fix with your v5 so as to keep the tree bisectable,
