We finally updated the MIPS toolchain to gcc-6.3, which got rid of the
other errors, but is now finding a few new ones, including an internal
compiler error.  :)   Arnd also mentioned that it's unlikely that the
qlge driver should be enabled for these defconfigs, so that's probably
an easy one.

Since it sounds so fun, I'll leave it with you MIPS folks to take care
of. ;)

Note that the same failures are happening in stable/linux-4.8.y and
stable/linux-4.9.y, so fixes should likely be CC'd to stable.

Thanks,

Kevin

The "0 errors" count is confusing here, I know.  Our error count
detection is not catching "gcc does not support" errors, so we need to
fix that.  The actual error message here is:

../arch/mips/sgi-ip22/Platform:29: *** gcc doesn't support needed
option -mr10k-cache-barrier=store.  Stop.
