ldb_config.h file missing about leveldb

[matthewvon]

(apologies for the delayed reply. Basho is effectively dead. All developers were laid off March 15, 2017. I have not been watching this repository closely since then.)

ldb_config.h is created at build time by the build_detect_platform script. Here is a sample from a Mac OS X build:

/** This file is generated by build_detect_platform.

• It saves the state of compile flags. This benefits the reuse
• of internal include files outside of a leveldb build.
  */

#ifndef OS_MACOSX
#define OS_MACOSX
#endif

#ifndef LEVELDB_PLATFORM_POSIX
#define LEVELDB_PLATFORM_POSIX
#endif

I suspect you will be able to quickly mock one up for your environment.
