You have lto enabled while this is noyt about to be supported by system libraries texlive compiles against, like cairo and others (I see you hit the cairo case exactly).

For cairo and various other stuff I have no-lto.conf exceptions. You probably
cannot see that from the build.log.

But I had indeed lto on for texlive-core. While that has been working up to
texlive-2017, disabling lto for texlive-2019 fixed the issue.

Thanks for the pointer.
