Summary: Some common build variables like USE_CLANG and COMPILE_WITH_UBSAN did not work if specified as make variables, as in `make USE_CLANG=1 check` etc. rather than (in theory less hygienic) `USE_CLANG=1 make check`. This patches Makefile to export some commonly used ones to build_detect_platform so that they work. (I'm skeptical of a broad `export` in Makefile because it's hard to predict how random make variables might affect various invoked tools.)

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 especially suitable for storing multiple terabytes of data in a single database.
