librocksdb_sys::bz_internal_error conflicts with bzip2-sys::bz_internal_error

[nikurt]

I'm getting the following link error due to the duplicate symbol when linking a binary with link-time optimizations:

   Compiling neard v0.0.0 (/home/nikurt/nearcore-rdb-3/neard)
warning: Linking globals named 'bz_internal_error': symbol multiply defined!

error: failed to load bc of "librocksdb_sys-33c86cdce183a558.librocksdb_sys.8e9e6b3e-cgu.0.rcgu.o":

warning: `neard` (bin "neard") generated 1 warning
error: could not compile `neard` due to previous error; 1 warning emitted
make: *** [Makefile:34: neard-release] Error 101

Symbols are defined here:

• librocksdb-sys:

  rust-rocksdb/librocksdb-sys/src/lib.rs

  Line 32 in 180e65e

  pub fn bz_internal_error(errcode: libc::c_int) {

• bzip2-sys: https://github.com/alexcrichton/bzip2-rs/blob/016e18155ef7c05983ea244cae1344c5b68defd8/bzip2-sys/lib.rs#L73

A workaround is to disable feature bzip2 of crate rocksdb.

Link-time optimizations defined in my Makefile as follows:

CARGO_PROFILE_RELEASE_LTO = fat

Is it possible to release a new version of the rocksdb crate in order to accommodate this change? The current version available on crates.io is 0.18.0 and it doesn't have all recent changes including this one. cc @aleksuss
