Summary: Fix g++ -march=native detection and reenable s390x in travis This PR fixes s390x assembler messages: ``` Error: invalid switch -march=z14 Error: unrecognized option -march=z14 ``` The s390x travis build was failing with gcc-7 because the assembler on ubuntu 16.04 is too old to recognize the z14 model so it doesn't work with -march=native on a z14 machine. It fixes the check for the -march=native flag so that the assembler will get called and correctly fail on ubuntu 16.04 which will cause the build to fall back to -march=z196 which works. The other changes are needed so builds work more consistently on s390x: 1. Set make parallelism to 1 for s390x: The default was 4 previously but I saw frequent internal compiler errors on travis probably due to low resources. The `platform_dependent` job works more consistently but is roughly 10 minutes slower although it varies. 2. Remove status_checked jobs, as we are relying on CircleCI for these now and do not really need platform coverage on them.

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.
