[v2] gcc 4.8.x does not compile a working kernel for sparc

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.

Committed, thanks.

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?

Yes.

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!
