Revert "Update BLST, add force-adx support (#1595)" (#1649)

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.

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).
Supports Intel Broadwell (2014) and newer, and AMD Ryzen (2017) and newer.
- `build-x86_64-portable`: builds a version for x86_64 processors which avoids using some modern CPU
instructions that are incompatible with older CPUs. Suitable for pre-Broadwell/Ryzen CPUs.
- `build-aarch64`: builds an optimized version for 64-bit ARM processors
- `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 for 64-bit ARM processors which avoids using some
modern CPU instructions. In practice, very few ARM processors lack the instructions necessary to
run the faster non-portable build.
- `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.
