* Cleanup the Arm64 CRC32 unused warning (#5565)
Summary:
When 'HAVE_ARM64_CRC' is set, the blew methods:
- bool rocksdb::crc32c::isSSE42()
- bool rocksdb::crc32c::isPCLMULQDQ()
are defined but not used, the unused-function is raised
when do rocksdb build.
This patch try to cleanup these warnings by add ifndef,
if it build under the HAVE_ARM64_CRC, we will not define
`isSSE42` and `isPCLMULQDQ`.

* Remove invalid comparison of va_list and nullptr (#5836)
Summary:
The comparison of va_list and nullptr is always False under any arch, and will raise invalid operands of types error in aarch64 env (`error: invalid operands of types ‘va_list {aka __va_list}’ and ‘std::nullptr_t’ to binary ‘operator!=’`).
This patch removes this invalid assert.

* Fix naming of library on PPC64LE (#6080)
Summary:
**NOTE**: This also needs to be back-ported to be 6.4.6
Fix a regression introduced in f2bf0b2 by https://github.com/facebook/rocksdb/pull/5674 whereby the compiled library would get the wrong name on PPC64LE platforms.
On PPC64LE, the regression caused the library to be named `librocksdbjni-linux64.so` instead of `librocksdbjni-linux-ppc64le.so`.
This PR corrects the name back to `librocksdbjni-linux-ppc64le.so` and also corrects the ordering of conditional arguments in the Makefile to match the expected order as defined in the documentation for Make.
