Prebuilt Clang/LLVM binaries can be really useful for exploration
since they might avoid a number of bootstrapping issues on new
platforms. For end users looking to try out Clang/LLVM/LLDB I suspect
they'll mostly just use packages provided by their OS, no? We'd also
need to sort out packaging for the python bits etc. But I'm happy to
build FreeBSD LLDB binaries (perhaps with python disabled?) if there's

I use the cmake build exclusively in my development and testing. Is
there any reason we wouldn't want to provide cmake-built binaries?
Note that the FreeBSD buildbot uses configure+make builds, and does
catch cases where only cmake gets updated.

For FreeBSD amd64 (64-bit x86) is the host platform being regularly
built and tested and that's the only one for which I can see providing
FreeBSD binaries. LLDB has been used on FreeBSD arm and ppc hosts as
