Please stop trying to build the removed architectures: tile, blackfin,
metag, m32r, frv, mn10300, cris and score.

https://lwn.net/Articles/748074/ has details about why this broke.

Note that we do have a few new architectures that you may want
to add if you haven't done this already: nds32 and riscv were added
this year, and a couple of older architectures that didn't have upstream
gcc releases now have those, and I uploaded gcc binaries to
https://cdn.kernel.org/pub/tools/crosstool/.

This should allow building everything we have in the kernel now.
Unfortunately the nds32 toolchain I uploaded is a little incomplete,
but I have a gcc-6.4 build that (mostly) works and gcc-8 should
be fine as well once it gets released.

Sorry about that!  It looks the architectures removal is not thorough
enough. Hao, would you help take a look?

OK, thanks for the tips! Philip may help plan add the 2 new archs
nds32 and riscv.

Thanks,

thanks for info, we will add new archs support in near future.

Thanks!  If you have any RISC-V questions feel free to ping me, but it should 
be pretty straight-forward as I think my trees are already in the system and 
our upstream toolchain works for Linux.
