Similarly canonicalize_file_name, dlopen, and getline - the first is a
GNUism, and we really should have a fallback if it is not found (there
is a usable gnulib version), but dlopen and getline?

Those are both standard calls now - dlopen is part of POSIX.1-2001 and
getline was added in POSIX.1-2008.

Are you compiling with an old or non-GNU libc?
