Matt,
I think source/Plugins/Process/gdb-remote/GDBRemoteCommunicationClient::GetRemoteQSupported () is lazily evaluated thanks to work by Steve Pucci in January (Thu 23/01/2014 21:04 [lldb-dev] [PATCH] new utility methods in GDBRemoteCommunicationClient)
That is, the qSupported is only sent when the debugger really needs to know about certain features like the SVR_4 library list - which would be irrelevant on a platform with no ld.so dynamic linker. Lldb should then start slightly faster than gdb for some scenarios.
