[Debian-med-packaging] Bug#806243: [MINC-development] Bug#806243: libminc: FTBFS on mipsel

[Robert D. Vincent]

Steve et al,

I used an emulated mipsel environment using some other distributions (found
here: https://people.debian.org/~aurel32/qemu/mipsel/) - the bug was not
reproducible. I am in the process of building a QEMU environment for a more
recent release ("sid" from 20151023), I will try that as soon as possible.
