bug#11645: Unable to cross compile guile 2.0.5 for MIPS/PPC on x86_64

Hi,

"Marinescu, Bogdan A" <address@hidden> skribis:

This is fixed by commit f3b312a19d70293d7a3407fc4ef479183edd7cca, which
will be in 2.0.6 (the fix was simple, but the investigation trickier ;-)).

There were only little-endian cross-compilation targets under continuous
integration, so I’ve added this one:
<http://hydra.nixos.org/jobset/gnu/guile-2-0>.

Thanks for the report!
