Subject: why is perf-report asking for objdump path?

$ /tmp/pbuild/perf report -i perf.data --kallsyms kallsyms
Error:
Please install objdump for i686.
You can add it to PATH, set CROSS_COMPILE or override the default using 
--objdump.

And worse it refuses to run without it. If I was running the annotate 
command I could understand the request -- but this is the report path.

Furthermore objdump exists:

$ which objdump
/usr/bin/objdump

yes, the file was created on an i686 target, but I should be able to use 
the x86_64 host objdump if I were doing an annotate.
