I'd like to bump bison-1.875 to stable on x86. It's been stable on other arches for a while now, and it's been ~x86 for a very long time. The only issues are on amd64 and k6 which can be easily fixed via filter-flags. I'll go ahead and commit fixes for amd64 and k6, then in a few days I'll bump 1.875 to stable x86 unless somebody complains in this bug.

Marked stable and committed.
