libc++ ABI namespace doesn't have to be just a number, it can be any [string
that starts with
`__`](https://github.com/llvm/llvm-project/blob/c557d8520413476221a4f3bf2b7b3fed17681691/libcxx/CMakeLists.txt#L197).
For example, in some of our Google projects we use `__ktl` and `__pw`.
[libFuzzer uses
`__Fuzzer`](https://github.com/llvm/llvm-project/blob/52ae891036e3ab1f668eb103c46ca57257901c6b/compiler-rt/lib/fuzzer/CMakeLists.txt#L166)
in its internal libc++ build.
