[lldb-dev] [Bug 20755] New: llgs: RSP qProcessInfo should return triple on Linux, not cputype/cpusubtype.

Hi Todd,

Will it still be possible that some non-Apple stuff (e.g. kalimba) can 
extract a subtype field (from say qProcessInfo or qHostInfo)? I'll need 
this to support kalimba architecture variants at some stage. (Bear in 
mind that CSR don't use share GDBRemoteCommunicationServer, only 
GDBRemoteCommunicationClient.

thanks,
Matt
