Users on small footprint systems probably use (or should use)
security/acmesh for this instead, so I don't consider that 
particular package a blocker.

This is first and foremost an LLVM limitation. At some point in
the future Rust-GCC should become a viable alternative.
FWIW I was able to build wip/py-cryptography on aarch64 with
ulimit -v 1048576; ulimit -m 1048576.
rustc needs around 900 MB. Should be OK on 512 MB (like old RPi)
with some swap I think.
