[lldb-dev] LLDB buildbot state

[Todd Fiala]

I just had a look at this build bot:

lldb-x86_64-linux

The latest build I looked at
here<http://lab.llvm.org:8011/builders/lldb-x86_64-linux/builds/10087>appears
to be failing because it doesn't have libedit installed.  As we
mentioned above, it will need a newer libedit since we are currently using
features that don't appear to be in older versions of the library and we're
not doing anything to distinguish that at the moment.
