This is the intended behavior. Please check:
https://bugzilla.yoctoproject.org/show_bug.cgi?id=3269

Also, this thread:

If people really need to install SDK tarballs intended for other hosts
than the SDK was built for (i686 on x86_64 or vice-versa), we could add
a -f flag to force installation and show an error message like this:

"Error: Installation machine not supported! Use -f to force installation."

Thanks,
Laurentiu
