commit c0be37352f6d91505d964a7d33ad79b40750d370
Author: Keno Fischer <keno@juliacomputing.com>

[CrossCompile] Add a dependency llvm-config-host -> llvm-tblgen-host
These use the same working directory and without a dependency
edge between them race to build some of the utility libraries
causing build failures.
