Since the switch to 4.8.x as default, the qemu-sparc target is broken.
For a gcc bug report see here:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=60624
Switch back to gcc 4.7.x as default for sparc.
Disable 4.8/4.9 as suggested by Thomas Petazzoni.
I even disabled gcc snapshot, it works right now, because
it is an old 4.8.0 snapshot by default, but as soon as this is updated
sparc build will break.

On a related note, this was presumably for the v8 variant? Do you know
if we still need to stick to gcc 4.4.x for the leon variants?

I have no idea. I asked about the price of a leon3 evaluation board
in the past, but 1000 euro was to high for me. The simulators are
non-free, so I could not try these. Do you have hardware or a
license for leon simulators? Who has added support for these
systems?
best regards
Waldemar

You should talk with Konrad Eisele <konrad@gaisler.com>, who added the
Leon Sparc support in Buildroot, and sent a couple of patches around
this topic in the past.
Thanks!
Thomas
