Test suite fails on x86

[msiebuhr]

The test suite fails when I try to run it on my machine.

When trying out the test/*.rrd-files with ex. rrdtool dump test/valid.rrd, I get:

ERROR: This RRD was created on another architecture

I therefor presume the test-files were created on a x64 machine, and my x86 can't make heads or tails of the data.

Could the data be generated by the test-suite itself, thereby also testing writing of files as well...
