CMake provides no interface for reading at configuration time
what flags the generator will produce later.

Somewhere there is code that says "if the compiler/platform
is X then add flag Y that affects the ABI".  Any place like
that should also add flag Y to a list that is later used
to put in LLVMConfig.cmake.
