[ Upstream commit a66fa0619a0ae3585ef09e9c33ecfb5c7c6cb72b ]
The callers of symbol__annotate2() use symbol__strerror_disassemble() to convert its failure returns into a human readable string, so propagate error values from functions it calls, starting with perf_env__arch() that when fails the right thing to do is to look at 'errno' to see why its possible call to uname() failed.
