[lldb-dev] Linux: Failing lldb unit tests and TestLinuxCore.py

[Pavel Labath via lldb-dev]

The BUILD_SHARED_LIBS part is likely to be the issue. LLDB libraries
have cyclic dependencies, which don't play well with shared libraries.
I think somebody "fixed" it some time ago (i.e., just made the flag be
ignored for lldb), but I'm not sure if he also checked the unit tests.
I'll see if I can reproduce that on my end.
