rG61cff9079c08: [BOLT] Support building bolt when LLVM_LINK_LLVM_DYLIB is ON
Summary

This does *not* link with libLLVM, but with static archives instead. Not
super-great, but at least the build works, which is probably better than
failing.

Related to #57551

Awesome, thank you for fixing the issue! Let me test the diff locally first.

Nice. Works for me. Do you think we really need this statement DISABLE_LLVM_LINK_LLVM_DYLIB in all CMakeLists, or just the ones that touch LLVM's Target libraries?
I've tried setting it only for bolt/lib/Target/*/CMakeLists.txt and it appears to build as well.

Sorry, it looks like we need to set it everywhere because otherwise some global symbols are present in both libLLVM and llvm-bolt and that causes a runtime crash:

$ bin/llvm-bolt --version
: CommandLine Error: Option 'aarch64-mark-bti-property' registered more than once!
LLVM ERROR: inconsistency in registered CommandLine options
Aborted (core dumped)

With that, LGTM. @rafaelauler @maksfb - please take a look if the change makes sense to you.
