Comment (by holin):

 I tested 8.5.1 with my changes and subsequent armhf builds appear to have
 identical SHA-256 sums, all languages.

 My arm tree assumes an arm64 builder host right now, but still supports
 building on armhf. It would be slightly cleaner (esp. projects
 /debootstrap-image) if armhf stuff was cleared out, and, I'll probably do
 that because building rust is way too unpredictable on 32-bit builder
 host. 64-bit built armhf binary seems to behave fine, and the above
 reproducibility was tested with 64-bit builder.

 Compared to my first 8.0 tree, I added gnu triplets to all targets, and I
 think having them would also be beneficial for cross building. The
 triplets could replace the arch variable as far as I can see.

 Cross building would seem to be much cleaner done if the build host had
 debian stretch base because of better apt multiarch support, but I haven't
 really done anything substantial towards cross building yet. Arm64 would
 likely require debian stretch level glibc regardless of how it's built.
