Doesn't work with Alpine linux

[ulrichard]

The binary that this crate downloads from bitcoincore.org doesn't run on an Alpine Docker container with
FROM alpine:3.15

The shared library ld-linux-x86-64.so.2 is missing and no compatible version available from the Alpine repo:

Also using the packaged version of bitcoind from the alpine repository doesn't work, because it was compiled without wallet functionality.
https://git.alpinelinux.org/aports/tree/community/bitcoin/APKBUILD line 51

I'm not sure what is the best way to make it work with Alpine.

It's too hard to provide binaries for every distro, I am afraid in this case you should build bitcoin locally and use the BITCOIND_EXE to tell the bitcoind crate where to look

We solved it by compiling the packages ourselves, and hosting them on a custom repo.
