Test suite failures on i386

[tillea]

Hi,
I intend to upgrade the Debian packaged version of xdffileio to version 1.0. We are building against the Debian packaged libmmlib version 1.4.2 which requires some patches which might be relevant for the issue.
The test suite passes nicely in our CI for amd64 architecture. However, for i386 we get:

Feel free to check the full build log on i386

Kind regards, Andreas.

@nbourdau Just an additional note: In case you consider i386 (or 32 bit in general) not supported architectures it would help if you would document this somewhere (at least here in this issue). We might exclude these architectures in Debian if there is no real chance to track down the issue above.
