rG8e1c989abbd1: Don't build and install {llvm,clang,lldb}-tblgen for the target

Summary

The tablegen binaries are only needed to build software that uses
LLVM's infrastructure for command line options,
disassembler tables, etc. They are not user-facing binaries and
should therefore not be installed by default.

Fine with me, assuming these are built using a different mechanism for the build toolchain itself.

While this is OK, I think we may even consider to avoid installing any of the tblgen tools *at all* in the base system. Other "extras" tools like llc, llvm-mc etc are usable by themselves, whereas the tblgen tools are really only needed for building llvm-project components.

That said, can you also add an entry to OptionalObsoleteFiles.inc for these? So they get cleaned up everybody that has MK_CLANG_EXTRAS=no.

don't install the tools at all
