Thread-topic: pcp2rrdtool qa/926 tweak
Hi Martins,

I'm getting reports of failures of qa/926 on exotic hardware -
e.g. s390x and ppc64 - with output like:

> ERROR in RRDs::info(./ganglia/gangliatest.64/load_fifteen.rrd) : This RRD was 
> created on another architecture

So, looks like the RRD format has more strict platform/arch needs
than we've realised  (i.e. the 32/64 bit check seems insufficient
and we may need arch-specific data/output) - I've made a change
to qa/926 to match this, could you verify that for me?  (working
well here)

Also, is there a recipe for gathering this ganglia test data?  I
could extract data from some of these hosts, and extend the test
coverage here.  We could perhaps put this recipe in the comment at
the head of the test too, for anyone else wanting to do this later.

cheers.
