Review request for KDE Software on Mac OS X and KDE Runtime.
Repository: kde-runtime
Description
-------
DrKonqi currently lacks support for lldb, which means KDE users on recent OS X versions cannot generate and submit post-mortem backtraces.
The patches in this RR introduce simple logic (based on *compile-time* OS version detection) to select either gdb or lldb, as well as appropriate lldbrc files.
This is the first step to be taken: determine when lldb should be launched, and how (to obtain a backtrace).
Diffs (updated)

Diff: https://git.reviewboard.kde.org/r/121286/diff/
Testing (updated)
-------
On OS X 10.9.4 with kdelibs git/4.14 .
Launching lldb works, as does the BatchCommand to obtain a backtrace; parsing of that information will be tackled later.
The backtrace isn't particularly useful though, because it doesn't (always/never/...?) display the location of the crash and steps leading up to it, *presumably* because of an issue in the interaction between KDE's crash reporter and lldb. This will need work...
