Error on 0.8 Nerves compile that worked on 0.7.3

I get this error:

** (Mix) Could not compile with "make" (exit status: 2).
You need to have gcc and make installed. If you are using
Ubuntu or any other Debian-based system, install the packages
"build-essential". Also install "erlang-dev" package if not
included in your Erlang/OTP version. If you're on Fedora, run
"dnf group install 'Development Tools'".

Repeats on CI and on my own Linux box.
This happens if I set my dependency to 0.8 instead of 0.7.3.

Anything I've missed in terms of different requirements for 0.8?

Looks specific to cross compilation, though I can't think of any specific change, beyond XLA itself.

ld: skipping incompatible cache/xla_extension/lib/libxla_extension.so when searching for -lxla_extension

This is confusing because the downloaded binary is for the target architecture.
