configs: remove qemu_sparc_ss10_defconfig

Since gcc 11 [1] the sparc architecture is disabled since
it produce a non working image. Buildroot now provide gcc
13.x, 12.x and 11.x and we are going to remove gcc 10
that was the last working release (thanks to a local patch).

First remove qemu_sparc_ss10_defconfig since it will no longer
be possible to build it with the internal toolchain backend.
