Hello,
I'm using buildroot 2010.02, configure it for sparc (not sparc64), also the
kernel is properly configured (sparc)
after make, (or make linux26, after building the toolchain etc) I get the
followin error in the last stage of kernel building !!

Any help ?! At least a useful debugging method !

--- Comment #1 from Thomas Petazzoni <thomas.petazzoni@free-electrons.com>  ---
Can you still reproduce the issue with Buildroot 2010.05 ?

It seems to be either a toolchain bug or a kernel bug (more likely a toolchain
bug). Sparc support in Buildroot isn't widely used, as Sparc isn't used much in
the embedded space.

--- Comment #2 from Thomas Petazzoni <thomas.petazzoni@free-electrons.com>  ---
As Sparc isn't really what we could call a CPU architecture widely used in
embedded systems, the core Buildroot team is not really willing to spend time
fixing Sparc related issues (we already have tons of other issues on more
important embedded architectures like ARM, PowerPC, MIPS, AVR32 and others).
So, unless someone (you ?) steps in with a fix for this, we are not going to
fix it.

We will probably mark the sparc and sparc64 architectures as deprecated in
Buildroot some day.
