It has been fixed, and the last reboot finally mounted a 10Gig swap too, 
so thats another problem addressed as the default 100Meg swapfile on the 
u-sd card is not big enough to assemble all of the rs-274-D interpreter 
in linuxcnc. Add the 10G swap and it marches straight thru it on the 
build. Now we just need to work around the missing dependencies that 
buster for armv7 has thrown at us.  And fixing that is well above my pay 
grade. Darnit.
