Currently x86_64, aarch64 and riscv64 are the only architectures using
the newer librsvg. Can you test the older librsvg-2.40 with the newer
cairo on x86_64 to see if the tests also fail there? I'm curious if it's
a 32-bit problem or if its just that old.

Overall I have no issues with skipping those two tests.
