[Lldb-commits] [PATCH] D13535: Fix cmake build on OSX after r249434.

This fixes the cmake build on OSX when building in a new workspace.   It reverts r249434 and instead fixes the issue as proposed in lldb-dev in message 'cmake question and [PATCH] for Undefined symbol "_liblldb_coreVersionString"'.  It gets the warning:
    ninja: warning: multiple rules generate tools/lldb/source/LLDB_vers.c. builds involving this target will not be correct; continuing anyway
(which no one was able to suggest a fix for in lldb-dev), but at least it fixes the problem without breaking the entire build :)
