package/ptm2human: new package

ptm2human is a decoder for trace data outputted by Program
Trace Macrocell (PTM) and Embedded Trace Macrocell (ETMv4).
It deconstructs ID packets and data packets from the
formatter of ARM Coresight ETB, and then translates the
trace data to a human-readable format.

+Subject: [PATCH] configure.ac: remove unneeded check for c++ compiler
+
+If the c++ compiler is not present, the build configuration
+will fail. This patch remove the check for the c++ compiler
+because all the ptm2human code is written in C.
