Sounds possibly similar to TARGET_ARCH=powerpc 's stack-handling SVR4 ABI violation when world is built by clang 3.8.0 (bad clang code generation). To get to the point of buildworld going through I had to change the kernel to provide a so-called "red-zone" on the stack during signal handling to protect the stack from being trashed. buildworld gets extensive signals (SIGCHLD) and so without the "red-zone" it would eventually get trashed addresses, far before getting near completion.

[Context: buildkernel via gcc 4.2.1 but buildworld via clang 3.8.0 .]

[Side note: I've tried aarch64 releng/11.0 (first RELEASE's raw) under qemu on Ubuntu 16.04.1 on the ODroid-C2 but it gots periodic illegal instructions in very basic operation, no builds active.]

[FYI: http://ameridroid.com/products/raspberry-pi-2-model-b-1gb-ram lists the RPi2B as both "out of stock" and "discontinued" and has for some time.]
