Great, thanks! Also, currently, we don't have any Sparc toolchain in
our autobuilder testing. Normally, we try to have all architectures we
support tested in our autobuilders. If we were to add the Sparc
architecture to our testing infrastructure, would you be willing to
look at the potential build failures that may result from this testing?
(Look at http://autobuild.buildroot.org to see what the results look
like for other architectures).

Thanks!
