LLDB on Linux

That Python path bug is fixed. But I'll check the other paths that can be requested using Host::GetLLDBPath and try to get them all correct using only relative paths (which seems the best choice. That should work for in-tree and installed builds using makefiles.

Nevertheless, lldb still hogs 100% CPU and does nothing on my machine.

I don't have a linux box handy, but I'm not seeing this on FreeBSD nor on Mac OS X.
Can you check where it's hanging? Try to get some stack traces and let us know.

BTW: Python 2.7 is needed, but only for some objc-formatters. I'm sending a fix for Python 2.6 today.
