^^^^^^^^^^
Warning 53 [misplaced-attribute]: the "deprecated" attribute cannot appear in this context

The relevant error message is

getconf: GNU_LIBC_VERSION: unknown variable

which comes from
https://github.com/janestreet/core_unix/blob/v0.16.0/unix_pseudo_terminal/src/discover.sh#L13
and getconf will return 2 if it doesn't know the variable, thus will
fail the build.
