We still use this for making gnu-compatible multilibs (that is, multilibs which use regular itanium vtables): https://github.com/llvm/llvm-project/blob/2c7b7eca85c2ccc9b0d5c65169213ce499652f92/clang/cmake/caches/Fuchsia-stage2.cmake#L200

AFAICT there doesn't seem to be a way where one can select the C++ ABI independently of the target platform.
