Thank you for reply. I had (possibly wrong) the impression that armv7 
CPU is compatible with instructions. At least i can perfectly run armv6 
binaries (e.g. rpi1 chroot) on armv7, despite the fact that it is 
"kern.supported_archs: aarch64 armv7". Also i was using this VM for a 
long time, just to build packages I am using for my old rpi1 (domoticz, 
ebusd, fresh libraries, etc). Now I am running full bulk and it seems to 
work fine.  I did a small patch to poudrier to make it possible [1], but 
it seems that upstream does not care about patches anymore.

Regarding bug 256132 - so far i cant find that it impacting my builds at 
all - binaries are running well. I could assume that some configure 
scripts could try to check (and enable) some flags for armv7 while 
building, but I think the chances are very low and it could be handled 
on ad-hoc basis.

Please correct me if i am missing something. Thank you, Oleksij
