I had a lot of unresolved Clang libraries related links problems when linking
lldb-gdbserver (from LLDB 3.6.1) on RHEL 6.

I was able to link after extracting link command and repeat in it Clang
libraries twice (immediately after first set). I tried to remove linker related
options (like -O3), but this didn't affect outcome.

My CMake configurations is:

${CMake}                                                                \
        -DCMAKE_BUILD_TYPE="Release"                                    \

Hi Eugene,

Please take top of tree. 3.6 is an arbitrary snapshot and lldb linux was not working then.
