kernelci reports a failure of the ip28_defconfig build after upgrading its gcc version: arch/mips/sgi-ip22/Platform:29: *** gcc doesn't support needed option -mr10k-cache-barrier=store. Stop. The problem apparently is that the -mr10k-cache-barrier=store option is now rejected for CPUs other than r10k. Explicitly including the CPU in the check fixes this and is safe because both options were introduced in gcc-4.4.
