Raspberry Pi 4 java.lang.UnsatisfiedLinkError

[loziniak]

Hello. I found that older versions (eg. 1.5.4) of Besu ran on Raspbery Pi without any significant modifications. Is arm64 platform supported? If not, how could I contribute to enable it? I work in Java :-)

Steps to Reproduce (Bug)

1. Log in to RPi
2. besu --min-gas-price=0 --data-path=data --genesis-file=../genesis.json --rpc-http-api=ETH,NET,IBFT --logging=INFO --bootnodes=enode://a6a5e740[,,,]@123.123.123.123:30303

Expected behavior: no errors

Actual behavior: I get these logs:

Perhaps this discussion here could help: facebook/rocksdb#5559

Patches welcome, please note also the work on besu-native required to use native dependencies.
