From: Christian Borntraeger <borntraeger@xxxxxxxxxx>
since 4.10 perf annotate exits on s390 with an "unknown error -95".
Turns out that commit 786c1b51844d ("perf annotate: Start supporting
cross arch annotation") added a hard requirement for architecture
support when objdump is used but only provided x86 and arm support.
Meanwhile power was added so lets add s390 as well.
While at it make sure to implement the branch and jump types.
