It turns out this week was particular bad for doing anything productive. Anyway, I found some time to fire up some cross compilers and it looks promising.
I used the cross compiler version 5.2.1 shipped by Fedora 23 and run allyesconfig/allmodconfig for ARM, ARM64, MIPS64, PPC64 (swait-v7 and 4.5-rc2). No new errors popped up.
With some luck I get some more architectures covered soon.
cheers, daniel
