Based on
https://github.com/llvm/llvm-project/blob/1c822e1e8278ebefdb7701249bdfe51f1ed03d7d/llvm/tools/llvm-shlib/CMakeLists.txt#L82-L85
it looks like `LLVM_BUILD_LLVM_C_DYLIB=ON` should definitely be supported on osx, however, actually setting it results in a build failure Iwhich might be a build ordering issue, because it cannot find `libLLVM.dylib`, which definitely gets built).
The stack trace below is from 17.0.0.rc2, but it has been the same for the 16.x series, and I presume it's the same for `main`. Xref also #43487.
