Going a different direction: Going to publish the build log
someplace? There is likely more there of interest to isolating
the issue(s).

I use META_MODE builds. One thing they do is record the
command used to try to produce each file. So in that kind
of context, identifying what it was trying to build allows
finding the related NAME.meta file and looking in it.

An example failure for armv7 and 1 GiByte of RAM could be
a simple memory allocation failure: unable to get a
sufficiently large contiguous range from the address space
for some request. (So it never gets to the point of using
swap for it.) Are you controlling how many threads the
linker uses?
