[lldb-dev] unable to build lldb 3.8

Wed Mar 16 03:10:07 PDT 2016

This is just a wild guess, but could you try running cmake with
-DLLVM_LIBDIR_SUFFIX=64. I remember we've had a need for that in the
past for systems which store libraries in lib64. Some provisions were
put in place to autodetect it, but i'm not sure if they completely
work.
