build.log on amd64
I'm hitting this on amd64, but not arm64 (I checked that the test doesn't get skipped on arm64)
The error is quite long, so not pasting it here. You can find it on line 21639 or by searching for document-link.test
This "version bump" removes option to not install sphinx by USE="-doc", please return this option (was OK in 10.0.0)
I get this test failure with clang-11.0.1 (on amd64).
