Summary:
The `#include "core_local.h"` was pulling in libgcc's `posix_memalign()`
declaration. That declaration specifies `throw()` whereas musl libc's
declaration does not. This was leading to the following compiler error
when using musl libc:

```
Since `#include "core_local.h"` is not actually used, we can just remove
it. I verified that fixes the build.
There was a related PR here (https://github.com/facebook/rocksdb/issues/2188), although the problem description is
slightly different.

RocksDB: A Persistent Key-Value Store for Flash and RAM Storage
RocksDB is developed and maintained by Facebook Database Engineering Team. It is built on earlier work on LevelDB by Sanjay Ghemawat (sanjay@google.com) and Jeff Dean (jeff@google.com)
This code is a library that forms the core building block for a fast key value server, especially suited for storing data on flash drives. It has a Log-Structured-Merge-Database (LSM) design with flexible tradeoffs between Write-Amplification-Factor (WAF), Read-Amplification-Factor (RAF) and Space-Amplification-Factor (SAF). It has multi-threaded compactions, making it specially suitable for storing multiple terabytes of data in a single database.
Start with example usage here: https://github.com/facebook/rocksdb/tree/master/examples
See the github wiki for more explanation.
The public interface is in include/. Callers should not include or
rely on the details of any other header files in this package. Those
internal APIs may be changed without warning.
Design discussions are conducted in https://www.facebook.com/groups/rocksdb.dev/
