Summary: To build on FreeBSD, arch_ppc_probe needs to be adapted to FreeBSD. Since FreeBSD uses elf_aux_info as an getauxval equivalent, use it and include necessary headers: - machine/cpu.h for PPC_FEATURE2_HAS_VEC_CRYPTO, - sys/auxv.h for elf_aux_info, - sys/elf_common.h for AT_HWCAP2. elf_aux_info isn't checked for being available, because it's available since FreeBSD 12.0. rocksdb assumes using Clang on FreeBSD, but powerpc* platforms switch to Clang only since 13.0. This patch makes rocksdb build on FreeBSD on powerpc64 and powerpc64le platforms.

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.

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.
