What do you mean by "normal" location? Our toolchain has `llvm-dwp` as `bin/llvm-dwp` which is the default location.

The builder description is correct, it's a Linux distribution (Debian) but we don't install GNU toolchains, we're strict about using Clang/LLVM toolchain which is why there's no `dwp`, just `llvm-dwp`. It's not just `dwp` though, we don't install any GNU tools and instead include the LLVM counterparts, for example `llvm-readelf` instead of `readelf`, `llvm-objcopy` instead of `objcopy`, etc.

It looks like `lldb/packages/Python/lldbsuite/test/make/Makefile.rules` assumes GNU toolchain, which seems a bit odd given that it's a part of LLVM. Would it be possible to make it compatible with both GNU and Clang/LLVM toolchains?
