+Subject: [PATCH] MDEV-30554 RockDB libatomic linking on riscv64
+
+The existing storage/rocksdb/CMakeCache.txt defined
+ATOMIC_EXTRA_LIBS when atomics where required. This was
+determined by the toplevel configure.cmake test
+(HAVE_GCC_C11_ATOMICS_WITH_LIBATOMIC).
+
+As build_rocksdb.cmake is included after ATOMIC_EXTRA_LIBS
+was set, we just need to use it. As such no riscv64
+specific macro is needed in build_rocksdb.cmake.
+
+As highlighted by Gianfranco Costamagna (@LocutusOfBorg)
+in #2472 overwriting SYSTEM_LIBS was problematic.
+This is corrected in case in future SYSTEM_LIBS is changed
+elsewhere.
+
+Closes #2472.
