sorry don't have any overview about mips at all.
But last patch is adding 4 defconfigs 32r2 and 64r2 (big and little)
endian.

I do use
.buildman-toolchains/gcc-4.9.0-nolibc/mips-linux/bin//mips-linux-gcc

And getting this when I change it to mips64r6
mips-linux-gcc: error: unrecognized argument in option '-march=mips64r6'

Are there any toolchain at generic location which buildman can use?

Thanks,
Michal
