Building the LLVM projects often means using the TableGen tools
(llvm-tblgen etc).
We currently build them as part of clang-native, but I am teasing the
clang recipe into its component parts and having to build llvm-native
or lldb-native simply for one tool isn't ideal.
Instead, add a native recipe that simply builds the tablegen binaries
for llvm, clang, and lldb
