the same diff is showing up in the kfreebsd-* build logs now. The
build there is done with -O2 though, so the provided patch is likely
not enough for fixing this.

I'm raising the severity to important because the package built
successfully there in the past, and this failure is now holding back
cmake, which in turn holds back a lot of other packages from being
built there.
