This is not the latest dev-libs/rocksdb version we have got in the tree, however it is still important because it's the newest version currently supported by sys-cluster/ceph. Moreover, the latest available version available in the tree at the moment, 6.17.3, explicitly declares RISC-V as unsupported.

6.15.5 fails to build the same way.
For the record, although a simple "append-libs -latomic" in the ebuild hasn't worked for me, adding string(APPEND CMAKE_CXX_STANDARD_LIBRARIES " -latomic") to CMakeLists.txt does make rocksdb-6.14.6-r1 build and install fine on rv64. For a proper solution, the check implemented in WebKit build scripts looks like it ought to work.
It seems this issue has been resolved in new upstream versions after 6.20* with similar CMakeList.txt changes.
