It seems worth it to open a bug to track the current support of camlboot
on different architectures.

x86_64-linux        supported (with substitutes)
i686-linux          supported (with substitutes)
aarch64-linux       unknown
armhf-linux         unknown
powerpc64le-linux   unknown

I test built camlboot on my aarch64-linux board, it stopped compilation
at ~55 hours with Signal 9 (OOM). 2GB RAM, 2GB swap.
