perf tools: Integrating the CoreSight decoding library
The Open CoreSight Decoding Library (openCSD) is a free and open library to decode traces collected by the CoreSight hardware infrastructure. This patch adds the required mechanic to recognise the presence of the openCSD library on a system and set up miscellaneous flags to be used in the compilation of the trace decoding feature.
