Hi Mark,

There was a discussion on the yocto mailing list about this:
https://lists.yoctoproject.org/pipermail/yocto/2013-January/013889.html

Also, a bug filed:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=3770

It turns out that people would like to be able to install 32-bit SDKs on
64-bit machines. Provided they have the 32-bit libraries in place.

Thanks,
Laurentiu
