[lldb-dev] gdb-remote to android gdbserver

[Virgile Bello]

Actually when I checked if it worked or not out of the box, I noticed one
missing thing was RLE (run-time length encoding) support in GDB remote
protocol.
I have a patch for that (change is quite small), that I can clean up and
upload soon if you are interested.
