Everything *not* on LLVM_DEFAULT train is likely incompatible e.g.,
breaking API changes or new compiler errors. Version checks may exist in
vendor code but rarely exposed in ports due to extra maintainence cost
for what is rarely tested non-default configuration.

Try removing such dependencies to understand why. There's no generic answer.

LLVM != Clang. Clang != libclang. Many consumers need libraries or
additional backends. If you want to avoid duplication remove crippled
base Clang.
