This reverts commit 4fca306397.
Something in the BLST update is causing SIGILLs on aarch64 non-portable builds. While we debug the issue, I think it's best if we just revert the update.

Cross-compiling
Lighthouse supports cross-compiling, allowing users to run a binary on one
platform (e.g., aarch64) that was compiled on another platform (e.g.,
x86_64).
Instructions
Cross-compiling requires Docker,
rustembedded/cross and for the
current user to be in the docker group.
The binaries will be created in the target/ directory of the Lighthouse
project.
Targets
The Makefile in the project contains four targets for cross-compiling:
build-x86_64: builds an optimized version for x86_64 processors (suitable for most users).build-x86_64-portable: builds a version x86_64 processors which avoids using some modern CPU instructions that might cause an "illegal instruction" error on older CPUs.build-aarch64: builds an optimized version for 64bit ARM processors (suitable for Raspberry Pi 4).build-aarch64-portable: builds a version 64 bit ARM processors which avoids using some modern CPU instructions that might cause an "illegal instruction" error on older CPUs.
Example
cd lighthouse
make build-aarch64
The lighthouse binary will be compiled inside a Docker container and placed
in lighthouse/target/aarch64-unknown-linux-gnu/release.
