* dist: precompiled binaries and Docker images The builds are reproducible, the binaries are portable and statically link librocksdb. This took some patching. Upstream PR: https://github.com/facebook/rocksdb/pull/9752 32-bit ARM is missing as a target because two different GCC versions fail with an ICE when trying to cross-compile RocksDB. Using Clang instead is too much trouble for a platform that nobody should be using anyway. (Clang doesn't come with its own target headers and libraries, can't be easily convinced to use the ones from GCC, so it needs an fs image from a 32-bit ARM distro - at which point I stopped caring). * CI: disable reproducibility test
