[ Upstream commit 28f4417c3333940b242af03d90214f713bbef232 ]
Callers of symbol__annotate() expect a errno value or some other extended error value range in symbol__strerror_disassemble() to convert to a proper error string, fix it when propagating a failure to find the arch specific annotation routines via arch__find(arch_name).
