Upstream as of 1.1.1 has R6 support the asm part and that was the main
culprit for the mipsr6 targets in 10-*. I smashed that into 20-* and
intend to keep it there for now. Once we move to 1.1.1 I would drop them
and switch to the R6 asm. That means we keep debian-mipsr6 targets and
drop linux-mips32r6 and so on. This is what I have now:

This should work for you, does it?

If you can help to forward, it will be great.

That part should go upstream. Do you want me to forward it or do you do
it yourself?

Bug#882007: openssl: add mips r6 support

[YunQiang Su]

Package: src:openssl
Version: 1.1.0g-2
X-Debbugs-Cc: hel...@subdivi.de

Please add mips r6 support of openssl.
mips r6 is quite similar with current mips architectures,
while mips r6 drops and replace some insn,
so they are not compatible with previous version.

Here for openssl, we disable ASM, and -DBN_DIV3W.
