hi,
perf build failed for me on s390x because of jitdump feature.
Attached patch tries to enable the build only on supported archs.
I haven't followed this feature too much, so I might have missed
something.. anyway it builds on s390x now ;-) I took the list of
archs from util/genelf.h
thanks,
jirka

Make jitdump being built only on architectures
defined in util/genelf.h file.
