Care to provide a config?
I was able to build qemu_sparc_ss10_defconfig switching to gcc 4.9.2 just fine
and it even boots.

Yup, qemu_sparc_ss10_defconfig works for me as well. The attached config (based
on a fresh checkout, "make menuconfig" and only minimal changes to the config
settings) doesn't build for me though.
