How to statically link everything?

[nullfs]

The Building a Distribution of LLVM guide mentions that:

The guidance for maximizing performance of the generated compiler is to use LTO, PGO, and statically link everything.

What options besides LLVM_STATIC_LINK_CXX_STDLIB would allow me to build a fully statically-linked version of clang and other LLVM tools?

[localspook]

There's the LLVM_BUILD_STATIC and LIBCLANG_BUILD_STATIC options

I tried it but it seems to cause build failures in LLDB.
