As a stopgap, you might consider adding a small swapfile and setting
swapiness to a low value.
Nearly every ARM gadget I had was suffering OOM kills on two C++
libraries that made heavy use of templates. The swapfile and
swappiness avoided most of the build problems I was encountering.
The SD Cards are dirt cheap, so I don't care if they wear them out 15%
faster than normal. Its an easier problem to solve than daily broken
